A girl has found valuable Viking treasures in a cornfield in Denmark with a metal detector. Among the almost 300 silver coins, which are around a thousand years old, are also Arabic and Germanic, as announced on Thursday by the Aalborg Historical Museum, which will house the treasures in the future.

The girl had taken part in an archaeological group expedition near the remains of the ring fortress Fyrkat last autumn and tracked down two larger treasures a few meters apart. From 1 July, the finds can be viewed in the museum in Aalborg. For the finder there should be a finder's reward in an undisclosed amount.

"A treasure like this is very rare," said museum director Lars Christian Norbach. According to their inscriptions, the silver coins were minted around the year 980. In addition to coins, according to the archaeologists, parts of a 500-gram piece of jewelry from Scotland or Ireland are also part of the find.

"What is surprising is that the treasure dates from the same period as the Viking fortress, which was built by King Harald Bluetooth, the founder of Denmark, so to speak," Norbach said. According to him, there could be a connection between the treasures that the Vikings buried in wartime and the fortress that burned down around the year 980.

Archaeologists plan to continue excavations in the fall, once the harvest season is over. They hope to come across remains of the houses and graves of the former owners.
