A man digging a garden terrace in Denmark struck something unusual. Then he realized he had found a Viking treasure including Thor's hammer

What began as an ordinary home improvement project has turned into one of Denmark’s most remarkable archaeological discoveries.

A man digging in his garden in Rebild, Denmark, was working on a new terrace when his spade hit something that sounded strange. He initially assumed he had encountered old iron, fence wire or pieces of pottery.

Instead, he had struck a Viking Age silver hoard weighing nearly 18.5 kilograms.


The discovery, made by a man who has requested anonymity, is now considered the largest known Viking Age silver hoard ever found in Denmark. It contains around 700 objects and fragments, dating to the 10th century—a period when Denmark was undergoing major political and religious changes.

He Thought He Had Found Scrap Metal

The discovery happened almost by accident.

After roughly half an hour of digging for his terrace, the man's spade struck something beneath the soil. The unusual sound caught his attention, but there was initially little reason to suspect anything extraordinary.

When he started digging with his hands, however, he began pulling out metal objects one after another.

Then came the realization: these weren't scraps. They were jewelry, coins and silver bars.

The objects had apparently been deposited together inside a clay vessel centuries ago, creating an archaeological time capsule beneath what would eventually become someone's garden.

Nearly Three Times Larger Than Denmark's Previous Record

The sheer size of the discovery is what makes it particularly extraordinary.

The hoard weighs almost 18.5kg, making it about three times heavier than the previous largest known Viking Age silver hoard in Denmark, the Terslev Hoard, which weighed approximately 6.5kg. Among the newly discovered objects are:

• Silver bars
• Bracelets
• 47 complete coins and additional coin fragments
• A small Thor's hammer
• Cut pieces of silver
• Coins carrying Arabic inscriptions
• A silver bar containing engraved runes

One of the runic inscriptions has been tentatively read as "hutu." Archaeologists believe it could potentially represent a name or an owner's mark, although its precise meaning still needs to be established.

The Silver Was More Than Money

According to Torben Sarauw, an archaeologist and head of cultural heritage at the North Jutland Museum, the discovery offers an unusually detailed look at how silver worked in Viking Age society.

Silver wasn't simply money in the modern sense.

It could circulate as coins, but it could also be weighed and divided into pieces and used as bullion for trading, making payments or storing wealth.

The mixture of intact coins, silver bars and cut silver therefore provides clues about the economic system that connected Viking communities with much wider trading networks.

And the Arabic inscriptions on some of the coins add another fascinating dimension.

They point toward the extensive connections between Scandinavia and the wider world during the Viking Age, when silver and other goods moved across enormous distances.

A Hoard From a Turning Point in Danish History

The treasure is important for another reason: when it was buried.

The 10th century was a transformative period for Denmark. The Danish kingdom was taking shape while Christianity was spreading through Scandinavia.

That means the objects aren't merely evidence of Viking wealth and commerce. They come from a period when the political structure and religious identity of Danish society were changing dramatically.

The presence of a small Thor's hammer alongside Christian-era influences makes the broader context particularly intriguing.

For archaeologists, the hoard could therefore help illuminate what life looked like at a moment when old beliefs, emerging Christianity, expanding political power and international trade were all intersecting.

From a Backyard to a Museum

The North Jutland Museums announced the discovery and will now undertake the painstaking process of documenting and studying the objects.

Once that work is completed, the hoard is expected to be exhibited at Fyrkat, the Viking Age ring fortress associated with King Harald Bluetooth and part of Denmark's UNESCO World Heritage site.

The journey from an anonymous backyard to a museum exhibition is an extraordinary one—but it also highlights how many pieces of Viking history may still be hidden beneath modern landscapes.

Metal detectorists account for a large share of recorded archaeological finds in Denmark; in 2024, they were responsible for 94% of recorded finds. Discoveries like this demonstrate just how much previously unknown evidence can emerge when objects are located, reported and carefully investigated.

For now, the biggest mystery remains unanswered: why was almost 18.5kg of silver buried there in the first place?

Was it a merchant's wealth? A carefully hidden fortune? An offering? Or something connected to the upheavals taking place across Denmark at the time?

The objects may eventually provide some answers—but the accidental discovery has already rewritten the scale of Denmark's known Viking silver treasures.
