Archaeologists on a Greek island have discovered a large Roman-era tomb containing gold jewelry, pottery and bronze offerings, officials said Wednesday.

The building, near the village of Fiscardo on Kefalonia, contained five burials including a large vaulted grave and a stone coffin, a Culture Ministry announcement said.

The complex, measuring 8 by 6 meters (26 by 20 feet), had been missed by grave-robbers, the announcement said.

Archaeologists found gold earrings and rings, gold leaves that may have been attached to ceremonial clothing, as well as glass and clay pots, bronze artifacts decorated with masks, a bronze lock and copper coins.

The vaulted grave, a house-shaped structure, had a small stone door that still works perfectly — turning on stone pivots.

On a nearby plot, archaeologists also located traces of what may have been a small theater with four rows of stone seats, the ministry said.

Previous excavations in the area have uncovered remains of houses, a baths complex and a cemetery, all dating to Roman times — between 146 B.C. and 330 A.D.
