More treasures are being unearthed during the construction of a new subway in the northern city of Thessaloniki, Greece’s second-largest city. The latest find is a gold wreath, the ninth unearthed since work started in 2006.

Found on the site of an ancient cemetery at what will be the Dimokratias Station stop, the wreath of olive leaves lay buried for some 2,300 years.

According to reports, the wreath was found “inside a large box-type Macedonian tomb on the head of a buried body.”

It was approximately dated to the Early Hellenistic Era, at the end of the fourth to early third century B.C.

Gold wreaths are rare finds and are usually associated with royal or aristocratic graves. Featuring delicate decorations which imitated various leaves, such as oak, olive, vine, laurel and myrtle, the fragile gold wreaths were created primarily for use as adornment of the deceased.

The finds will go on display at the Thessaloniki Archaeological Museum after conservation.
