Four 1 800-year-old Roman graves have been uncovered during road works in the northern Greek city of Veroia, the Culture Ministry said Friday.

A statement said two gold earrings, a copper coin and ceramic pots were also found at the site, were municipal workers had been laying paving stones and upgrading the water supply network.

The graves are believed to be part of a Roman cemetery discovered in the 1960s outside the city's ancient walls.

Ancient artifacts are often discovered during public works in Greece, where many cities and towns date back to antiquity.

A massive horde of antiquities uncovered while building a new subway system in Athens, which opened in 2000, with extensions added before the 2004 Olympics. Some of the discoveries are on display at Athens stations.
