Rare, 1,000-year-old Viking Age iron hoard found in a basement in Norway

A rare stash of 1,000-year-old ironwork, which sat for 40 years in a family’s basement in Norway, is now seeing the light of day after a woman discovered the hoard during some spring cleaning. 

The hoard consists of 32 iron ingots that look like small spatulas and date back to the Viking Age (A.D. 793 to 1066) or the high Middle Ages (1066 to 1350). The rods are identical and weigh about 1.8 ounces (50 grams) each, prompting archeologists to think they may have been used as a form of currency and that someone probably buried them with the intention of coming back for the treasure later.

“We call it a cache find because it is clear that someone has [buried it] to hide it,” Kjetil Loftsgarden, an archeologist and associate professor at the University of Oslo and the Museum of Cultural History in Oslo, told NRK News. Each ingot is pierced with a hole on one end, which suggests the ingots could have been tied together in a bunch, experts added.

While similar ironwork already exists in the museum’s collections, this discovery is rare because construction projects often destroy or damage buried treasures, Loftsgarden said. In this case, Grete Margot Sørum, who came across the treasure trove while clearing out her parents’ basement in Valdres, central Norway, told NRK News that she remembers her father finding the stash while he dug a well by the house in the 1980s. “But then he put them away in a corner,” Sørum said.

The last time someone unearthed a hoard of iron ingots in Valdres was 100 years ago, according to NRK News.

From the late Viking Age until the high Middle Ages, independent farmers in southern Norway produced iron on a massive scale, according to a 2019 study by Loftsgarden, published in Fornvännen, the Journal of Swedish Antiquarian Research.

The region was so productive that there was a surplus of iron, which traders sold to elites in the more populated coastal regions of Norway.

Sørum’s father unearthed the ingots from a site located along the Bergen Royal Road, known as Kongevegen, which served as a trade route between Oslo and Bergen 1,000 years ago.

The area around the site was dotted with charcoal pits, which were indispensable to iron production for smelting during the Viking and Middle Ages, Loftsgarden wrote in the study.

Sørum notified the Valdres Folkemuseum in Fagernes, which then forwarded the iron collection to the Cultural Heritage section of the Innlandet county municipality. The iron hoard is now stored at the Cultural History Museum in Oslo, where archeologists will study and catalog the artifacts.

“Old finds that are handed into the archeologists provide new knowledge about the history of the Inland,” Anne Engesveen, unit leader for archeology at the Cultural Heritage section, said in a statement.

The discovery of the iron collection in the Sørum family basement is not the first Viking find from Norway in recent months. In November 2022, a metal detectorist stumbled across a Viking treasure hoard consisting of a pair of silver rings, fragments of a silver bracelet, and what look like chopped-up Arabic coins, among other buried artifacts. 

Ruins of the 700-year-old wharf, possibly used by royalty, were found in Oslo

An excavation by NIKU archaeologists in Oslo’s seaside neighborhood of Bjørvika has uncovered the remains of a long section of a medieval wharf believed to have been built by a medieval king of Norway.

Under the dense clay of the Oslofjord seabed, more than 26 feet of the pier’s foundations have persisted in excellent condition.

Archaeologists knew from preliminary surveys that something was buried at a port in Oslo, the Norwegian Institute for Cultural Heritage Research (NIKU) said in a Thursday, March 2, news release. The ruins of a medieval wharf were discovered when excavations got underway.

The wharf consisted of massive logs lashed together to form bulwarks. The logs were dotted with impressions of barnacles and mussels, signs of having once been exposed to the sea.

Over time, the structures built on top of the foundations pressed them deeper into the clay, where they remained even after the surface structures were lost.

The pier was most likely built in the early 14th century and has since sunk into the clay seabed under its own weight, according to the release.

Archaeologists believe this wharf was probably the king’s, based on its location and estimated age. Another nearby dock is known to have been used by royalty from the 11th to 13th centuries, according to the release.

A small mystery is that archaeologists unearthed layers of food waste, fish bones, dung, and peat in the clay around the massive logs. Archaeologists don’t know how these materials ended up around the pier.

“This is very mysterious,” says Håvard Hegdal, archaeologist and project manager from NIKU, “How has this come into what has been a closed construction? There has been a floor above us, and probably a building, and it shouldn’t be possible to throw food scraps and other things down here.”

“There was also a lot of dirt from a boat inside these layers. And it shouldn’t have come in here in any case. So ‘King’s wharf’ may have had a reasonably short lifespan, and that is quite strange.”

Researchers will cut a portion of the wood off the pier and send it to a lab to be more specifically dated dendrochronologically, the release said.

The most likely candidate to build the wharf was Haakon V (reigned 1299–1319). Oslo overtook Bergen to become the capital of Norway during his reign, and Haakon had the Akershus Fortress built to protect the city and serve as a royal residence. The pier’s foundations were discovered right next to the ruins of the royal palace that stood before Akershus Fortress.

The remains of the wharf have been scanned to create a 3D model. And excavations are ongoing.

Archaeologists surprised when 3,500 year old arrowheads made of shells melted out of the ice in the Norwegian mountains

Unique arrowheads made of freshwater pearl mussel have melted out of the ice in the mountains in Jotunheimen in Norway. Arrowheads like this have not been found anywhere else in the world, according to archaeologist.

They were in use only a couple of hundred years, and nobody knows why.

“Why they chose to use shells to make arrowheads is something to ponder,” says archaeologist Lars Pilø.

“Folks at the time did have access to stone which can be used to make arrowheads, and they also used bone and antlers,” he says.

Melting out of the ice

Pilø is an archaeologist in Innlandet County Municipality where he heads the renowned glacier archaeological program Secrets of the Ice. Archaeologists have collected several thousands of finds from glaciers and ice patches in the Norwegian mountains since the onset of the program in 2011.

“Our glacial archaeologists were very surprised when the first arrowhead made from mussel shells melted out the ice. Now they have found a total of three,” Pilø tells sciencenorway.no.

In addition, some such arrowheads have been found in two other locations in mid-Norway.

“We have also found arrow shafts with the same type of fixing. These have most likely also had shell arrowheads,” Pilø says.

The archaeologists have also found the sinew used to bind the arrowheads. At the other end of the arrow, the shaft has been fitted with feathers. The arrowheads are probably made out of freshwater pearl mussels – Margaritifera margaritifera.

Short time period

The finds were made in a small area, and stem from a short time period.

“This has been a short-lived tradition, from the Early Bronze Age around 3,700 to 3,500 years ago,” Pilø says.

The freshwater pearl mussels have probably not existed in the areas where the arrowheads were found. The arrows have apparently been made in the lowlands, and then hunters have brought them up in the mountains to go hunting.

When several thousands of years old ice melts, archaeologists are finding incredibly well-preserved items.

“Objects that have been encapsulated in the ice have in a way become frozen in time. They don’t age. This way also the organic material is preserved,” Pilø explains.

A different kind of find

Professor of archaeology Christopher Prescott at the University of Oslo also talks about these unique conditions of preservation:

“Mountain archaeology has a long history in Norway. The interesting things is that they can find these organic components,” he says.

Usually, when archaeologists excavate an open area, they only find the hardest materials.

“We know that human culture also consists of many other things. I have myself found pearls made from mother of pearl which were more than 4,000 years old. Shells are a part of this type of find, but as far as I know this is one of few or perhaps the first time that such arrowheads made from shells have been found,” Prescott says.

Going hunting

And in keeping with this, Lars Pilø talks about the find as breaking news.

“Arrowheads made from mussels were completely unknown in Norway before the melting started, and they have not been found anywhere else in the world,” he says.

What archaeologists do not know yet, however, is what it was like to go hunting with shell arrowheads.

“The only way to find out is to do experimental archaeology, meaning we will make and try to shoot with a few different types of arrowheads,” Pilø says.

“For the hunter this was about needing the arrowhead to penetrate the animal and create a proper wound. I would imagine that sharp mussels are quite well suited to do so,” he says.

Oldest shoe in Norway, dating to 3,000 years ago, recovered from melting ice patch

The oldest shoe in Norway — a 3,000-year-old bootie from the Bronze Age — is just one of thousands of ancient artifacts that were recovered from the country’s melting mountain ice patches in the past two decades, according to a new report from the Norwegian University of Science and Technology (NTNU).

Unlike objects trapped in acidic soil or beneath gargantuan glaciers, the artifacts recovered from Norwegian ice patches are often found in impeccable condition, showing minimal decomposition and deformation, even after thousands of years of frozen slumber. That’s because ice patches are relatively stable, unmoving and free from corrosive compounds.

Perfectly intact weapons, clothing, textiles, and plant and animal remains have all emerged from the ice, helping to bring thousands of years of Norwegian history to light.

But now, the report authors said, climate change could bring that all to an end.

Within just a few decades, vast swaths of Norway’s ice patches have begun to melt, exposing undiscovered artifacts to the elements and almost certain deterioration, the authors wrote.

“A survey based on satellite images taken in 2020 shows that more than 40 percent of 10 selected ice patches with known finds have melted away,” report co-author Birgitte Skar, an archaeologist and associate professor at the NTNU University Museum, said in a statement. “These figures suggest a significant threat for preserving discoveries from the ice, not to mention the ice as a climate archive.”

The melting past

Ice patches form at high elevations, where snow and ice deposits accumulate and don’t completely melt in the summer. Unlike glaciers, ice patches don’t move, so objects deposited in ice patches can remain stable for hundreds or thousands of years.

When the ice begins to melt, those objects return to the light of day, preserved just as they were when the ice swallowed them up. However, if scientists aren’t able to recover these objects soon after the melting begins, then they run the risk of losing the artifacts to the elements.

Ice patch archaeology has been a tremendous boon to researchers studying the ancient cultures, plants and animals in frosty, elevated regions around the world. In Norway, researchers have uncovered thousands of artifacts belonging to the Bronze Age hunting tribes who hunted reindeer across Northern Europe and southern Scandinavia.

According to the new report, reindeer are drawn to the region’s mountainous ice patches in summer months to seek relief from biting insects and the heat. Where the reindeer went, hunters followed, leaving troves of artifacts behind.

The 3,000-year-old shoe, which was discovered in 2007 in the mountainous region of Jotunheimen in southern Norway, remains a standout find. The small leather shoe would be a size 4 or 5 in today’s U.S. sizes, suggesting it belonged either to a woman or a youth.

The shoe was discovered alongside several arrows and a wooden spade, suggesting the site was an important hunting ground. Dated to approximately 1100 B.C., the shoe is not only the oldest shoe in Norway, but possibly the oldest article of clothing discovered in Scandinavia, according to the researchers who discovered it.

Further surveys of the Jotunheimen site revealed even older artifacts, including a 6,100-year-old arrow shaft — the single oldest object discovered in a Norwegian ice patch, according to the researchers. Its presence near the shoe, suggests that the site was continuously used by humans over many millennia.

Despite these remarkable finds, the report authors worry that countless other cultural artifacts could disappear before they are recovered, thanks to the effects of climate change. A 2022 report from the Norwegian Water Resources and Energy Directorate estimates that 140 square miles (364 square kilometers) of ice patches — an area roughly half the size of New York City — have melted since 2006. If artifacts are not recovered from these patches soon after they are exposed, they risk being lost, damaged or destroyed forever.

Few ice patches in Norway have been systematically surveyed, especially in northern Norway, which remains mostly unstudied. To mitigate this, the researchers suggest launching a national ice patch monitoring program, using remote sensors to systematically survey ice patches and secure any objects that emerge from the melt.

“We used to think of the ice as desolate and lifeless and therefore not very important. That’s changing now, but it’s urgent,” report co-author Jørgen Rosvold, a biologist and assistant research director at the Norwegian Institute for Nature Research, said in the statement. “Large amounts of unique material are melting out and disappearing forever.”

Reconstruction Shows Teen Who Died in Norway 8,300 Years Ago

About 8,300 years ago, a teenage boy with an unusual skull and short stature may have scampered along the rocky coast of what is now Norway, pausing to regain his balance as he clutched a fishing rod. Now, a new full-body reconstruction of the Stone Age teenager — nicknamed Vistegutten, Norwegian for “the boy from Viste” — is on display at the Hå Gamle Prestegard museum in southern Norway.

The boy’s reconstruction was a months-long project, but researchers have known about Vistegutten since 1907, when archaeologists found his remains in a Mesolithic, or Middle Stone Age, cave in Randaberg, along Norway’s western coast. 

A few things stand out about the 15-year-old boy: At 4 feet, 1 inch (1.25 meters) tall, he was short for his age, even by Mesolithic standards; a condition known as scaphocephaly meant that his skull had fused too early, forcing his head to grow backward instead of sideways; and he may have died alone, as his remains were found as if he had been leaning against a cave wall. 

“Either he was placed like this after his death, or he actually died in this position,” Oscar Nilsson, a forensic artist based in Sweden who created the boy’s likeness, told Live Science in an email. “This can give the impression of a lonely boy, waiting in vain for his friends and family to show up … but we know nothing about how he died.”

Scaphocephaly occurs when the sagittal suture on the top of the skull fuses too early, giving the skull a ridged appearance. But “it is not associated with any developmental problems or intellectual disabilities,” Sean Dexter Denham, an osteologist at the Museum of Archaeology at the University of Stavanger in Norway who helped analyze the skeleton, told Live Science in an email. And while the boy’s unusual skull and short stature may have given him a unique appearance, his remains suggest he was well-fed and healthy. 

“The sheer volume of animal remains found at the site also attests to a plentiful food supply,” Denham said. The cave, which is about 30 feet (9 m) deep and 16 feet (5 m) wide, is filled with kitchen waste; ornaments, such as decorated bone pendants; and fishing tools, including hooks, harpoons and barbed bone points, suggesting that ancient “people lived, worked, cooked and slept at the Viste site,” Nilsson said. 

“The fishing hook that the reconstruction of the boy from Viste holds in his hand is a replica of one of these findings,” Nilsson noted. 

To make the reconstruction, two computed tomography (CT) scans were taken of the skull, allowing Nilsson to create a 3D-printed plastic replica. Because he wasn’t sure about the boy’s facial tissue thickness, Nilsson relied on measurements of modern Northern European 15-year-old boys. “Of course, we don’t know how transferable these measurements are to someone who lived 8,000 years ago,” Nilsson said. “But it’s the best we can guess.”

He noticed that the forehead was “quite childish in appearance, rounded and projecting from the face a bit. This is most probably coming from the scaphocephaly,” Nilsson said, adding that the teenager also had a thin nasal ridge but a nose that was “rather broad at the lower parts.” 

An analysis of the boy’s DNA showed that his skin tone, hair, and eye color “likely would be close to the other ‘Norwegian’ findings from the period,” including mostly brown eyes, dark hair, and intermediate skin tone, Nilsson added. 

He intended to give the teenager a subtle smile, “but as I got deeper into the project, I could not get rid of a feeling of a lonely boy,” Nilsson said. “I imagine him on his way to the sea (which at his time was extremely near the cave) to catch some fish. It is very windy in this part of Norway, so I worked quite a lot to make it look as if the wind blows in his hair and clothes.”

Stone Age wardrobe

The boy’s clothes are made by Helena Gjaerum, a Sweden-based independent archaeologist who uses prehistoric techniques for tanning leather. “Oscar wanted a summer outfit and that the boy would be barefoot, standing on the beach,” Gjaerum told Live Science in an email. “Therefore, a tunic was decided from the beginning.”

She made the tunic from de-haired and fat-tanned elk skin, and put two bark-tanned salmon skins around his waist. A bag that hangs off his belt was sewn from deerskin. All of these animals’ remains were found at the archaeological site. To add to the authenticity, “The suit is sewn with both sinew thread and leather straps,” Gjaerum explained. “It is smeared with ash and grease to look believable.”

The boy’s necklace was crafted from salmon vertebrae and a broken seashell. His remains are “one of the oldest skeletons ever found in Norway,” Kristine Orestad Sørgaard, an archaeologist at the Museum of Archaeology at the University of Stavanger who helped Nilsson understand the archaeological context, told Live Science in an email. “It’s a great reminder that people in the past were very much like us, despite living in a world very different from our own.”

World’s oldest runestone found in Norway, archaeologists say

Archaeologists in Norway have found what they claim is the world’s oldest runestone, saying the inscriptions are up to 2,000 years old and date back to the earliest days of the enigmatic history of runic writing.

The flat, square block of brownish sandstone has carved scribbles, which may be the earliest example of words recorded in writing in Scandinavia, the Museum of Cultural History in Oslo said.

It said it was “among the oldest runic inscriptions ever found” and “the oldest datable runestone in the world”.

“This find will give us a lot of knowledge about the use of runes in the early iron age. This may be one of the first attempts to use runes in Norway and Scandinavia on stone,” said Kristel Zilmer, a professor at the University of Oslo, of which the museum is part.

Older runes have been found on other items, but not on stone. The earliest runic find is on a bone comb found in Denmark. Zilmer said that maybe the tip of a knife or a needle was used to carve the runes.

The runestone was discovered in late 2021 during an excavation of a grave near Tyrifjord, west of Oslo, in a region known for several monumental archaeological finds. Items in the cremation pit – burned bones and charcoal – indicate that the runes were likely inscribed between AD1 and AD250.

“We needed time to analyse and date the runestone,” she said to explain why the finding was first announced on Tuesday.

Measuring 31cm by 32cm (12.2in by 12.6in), the stone has several types of inscriptions and not all make linguistic sense. Eight runes on the front of the stone read “idiberug” – which could be the name of a woman, a man or a family.

Zilmer called the discovery “the most sensational thing that I, as an academic, have had”.

There is still a lot of research to be done on the rock, dubbed the Svingerud stone after the site where it was found.

“Without doubt, we will obtain valuable knowledge about the early history of runic writing,” Zilmer said.

The runestone will be exhibited for a month, starting on 21 January, at the Museum of Cultural History, which has Norway’s largest collection of historical artifacts, from the stone age to modern times.

Runes are the characters in several Germanic alphabets that were used in northern Europe from ancient times until the adoption of the Latin alphabet. They have been found on stones and different household objects.

New study investigates the development of the Scandinavian gene pool over the latest 2000 years

A new study resolves the complex relations between geography, ancestry, and gene flow in Scandinavia – encompassing the Roman Age, the Viking Age, and later periods.

Researchers investigated a 2,000-year genetic transect through Scandinavia spanning the Iron Age to the present, based on 48 new and 249 published ancient genomes and genotypes from 16,638 modern individuals.

A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially intense during this period.

An international study coordinated from Stockholm and Reykjavik investigates the development of the Scandinavian gene pool over the latest 2000 years. In this effort the scientists relied on historic and prehistoric genomes, and from material excavated in Scandinavia.

These ancient genomes were compared with genomic data from 16,638 contemporary Scandinavians. As the geographical origin and the datings were known for all these individuals, it was possible to resolve the development of the gene pool to a level never realised previously.

Dr Ricardo Rodríguez Varela at the Centre for Palaeogenetics*, who analyzed all the data and extracted some of the ancient DNA used in the study, explains: “With this level of resolution we not only confirm the Viking Age migration.

We are also able to trace it to the east Baltic region, the British-Irish Isles and southern Europe. But not all parts of Scandinavia received the same amounts of gene flow from these areas. For example, while British-Irish ancestry became widespread in Scandinavia the eastern-Baltic ancestry mainly reached Gotland and central Sweden.”

The gene pool bounced back after the Viking period

Another new discovery in this study was what happened to the gene pool after the Viking period. The scientists were surprised to find that it bounced back in the direction of what it looked like before the Viking period migration.

Professor Anders Götherström at the Centre for Palaeogenetics, who is a senior scientist on the study, is intrigued: “Interestingly, the non-local ancestry peaks during the Viking period while being lower before and after.

The drop in current levels of external ancestry suggests that the Viking-period migrants got less children, or somehow contributed proportionally less to the gene pool than the people who were already in Scandinavia.”

Yet a new discovery was the history of the northern Scandinavian gene pool. There is a genetic component in northern Scandinavia that is rare in central and western Europe, and scientists were able to track this component in northern Scandinavia through the latest 1000 years.

Dr Ricardo Rodríguez Varela comments, “We suspected that there was a chronology to the northern Scandinavian gene pool, and it did indeed prove that a more recent influx of Uralic ancestry into Scandinavia define much of the northern gene pool. But if it is recent, it is comparatively so. For example, we know that this Uralic ancestry was present in northern Scandinavia as early as during the late Viking period”.

Based on well-known Swedish archaeological sites

The study is based on a number of well-known Swedish archaeological sites. For example, there are genomes from the 17th century warship Kronan, from the Viking and Vendel period boat burials in the lake Mälaren Valley, and from the migration period ring fortress Sandby borg on Öland.

Anders Götherström conclude: “We were working on a number of smaller studies on different archaeological sites. And at some point it just made sense to combine them into a larger study on the development of the Scandinavian gene pool.

The study, published today in Cell, is an international effort with several collaborators, but it was led by Dr Ricardo Rodríguez Varela and Professor Anders Götherstörm at Stockholm University, and Professor Agnar Helgason, and Kristjáan Moore at deCODE in Reykavijk.

The article “The genetic history of Scandinavia from the Roman Iron Age to the present” is published in Cell.

A large hall from the time of Viking Harald Bluetooth discovered

A large hall from the reign of King Harald Bluetooth of Norway was unearthed during housing construction work near Hune, a village in the Jammerbugt Municipality of North Jutland, Denmark.

The hall was up to 40 meters long and 8-10 meters wide, with 10-12 oak posts supporting the roof. They are rectangular in cross-section and measure up to 90×50 cm.

The hall probably served as a crucial location for political gatherings, for hosting visitors, and as the hub of social activity in the community’s social life.

Preliminary dating places the hall in the last half of the ninth century or the very first part of the eleventh century, but it was probably in use during the reign of Harald Bluetooth.

A rune stone near the excavation site has a date that fits this time frame. The stone, which dates from between 970 and 1020, is located in Hune Kirke and is inscribed with the words “Hove, Thorkild, and Thorbjrn set their father Runulv den Rdnilde’s stone.”

The hall’s design is reminiscent of structures found at Harald Bluetooth’s ring castles, including Fyrkat at Hobro and Aggersborg at Aggersund.

The researchers have only excavated a portion of the hall, but they believe that additional buildings and features lie beneath the surface to the east of the hall, as buildings of this type rarely stand alone.

Thomas Rune Knudsen, from North Jutland Museums said: “This is the largest Viking Age find of this nature in more than ten years, and we have not seen anything like it before here in North Jutland.”

Excavations will resume in the New Year, with a Carbon-14 analysis on organic remains for more accurate dating, the results of which are expected to be published by the end of 2023.

King Harald Bluetooth, a Viking-born king who turned his back on old Norse religion and converting to Christianity. He is noted for bringing Christianity to Denmark and earned the nickname Blåtand (meaning blue tooth) because of a dead tooth that is said to have been dark blue.
