Archaeologists in Turkey have uncovered a sarcophagus that may belong to Saint Nicholas, the 4th-century bishop who inspired Santa Claus.

Found in a 7th-century church built in his honor in Myra (modern-day Antalya), the limestone sarcophagus is about 6 feet long and 5 feet deep, buried 6 feet underground.

Researchers hope to find an inscription to confirm its contents and dating.

Saint Nicholas was originally buried in Myra, but his bones were believed to have been moved to Venice after the First Crusade, the New York Post has reported.

While bones in Venice and Bari were confirmed to belong to the same individual, it’s still unclear if they are truly Saint Nicholas.
