Archaeologists have been left at a loss by the discovery of some mysterious ruins in Rome, which could be the remains of one of the city's earliest churches. The find was made at Ponte Milvio, a bridge along the River Tiber in the northern part of the city. And it came about completely by chance while electrical technicians, who were laying cables along the site, uncovered remains of buildings dating back to between the first and fourth century AD.
Rome's Archaeological Superintendency called the discovery "an archaeological enigma shrouded in mystery". Part of these remains look likely to have been used as a warehouse, but it's an older building on the higher level that has presented archaeologists with a mystery.
