A family from Norway was looking for a lost gold earring in their garden when they decided to use a metal detector. They did not find the earrings, but they “came across” something else: artifacts that are more than 1,000 years old, the BBC reports.

The Aasvik family discovered a buckle and another object that was believed to have been used in a Viking Age burial.

Experts believe that these artifacts were used to bury a 9th-century woman on the small island of Jomfruland.

The discovery was made under a large tree in the center of a family garden on a Norwegian island.

Vestfold Cultural Heritage and Telemark County Council wrote that this is the first time anyone has found items dating back to the Viking Age in Jomfruland.

Experts knew there were settlements on the island dating back hundreds of years, but evidence only went back to the Middle Ages.

One expert has concluded that this buckle dates to between 780 and 850.
