Ancient graves found in Greece

Greek workers discovered around 1,000 graves, some filled with ancient treasures, while excavating for a subway system in the historic city of Thessaloniki, the state archaeological authority said Monday.

Some of the graves, which dated from the first century B.C. to the 5th century A.D., contained jewelry, coins and various pieces of art, the Greek archaeological service said in a statement.

Thessaloniki was founded around 315 B.C. and flourished during the Roman and Byzantine eras. Today it is the Mediterranean country's second largest city.
