The metro construction in Greece's Thessaloniki has brought ancient ruins of the city's life back in the 6th century to the surface. The excavation has uncovered jewellery, 50,000 coins, an early Christian church and many more items.The excavation has brought to light Thessaloniki's central 6th-century highway and other urban works, filling in gaps in the city's long history for archaeologists.Other finds such as the villa are older, dating to the late fourth century AD. On the floor of the villa's hot bath, archaeologists found a gold ring. "It was probably dropped by a young woman who made the mistake of taking her jewellery into the baths," a site archaeologist said.Golden wreaths and jewellery were also found in over 5,000 graves and tombs along the subway route,
