The Catacombs of Saints Marcellinus and Peter

The catacomb of Peter and Marcellinus is a major attraction in Rome, located on the ancient Via Labicana, south-east of the city and 3 kilometres from the ancient town's walls. You can join a guide to explore a vast network of subterranean galleries, 4.5 kms long, spanning three levels across an area of three hectares. This complex catacomb is the final resting place of saints Peter and Marcellinus as well as up to 25,000 more people. It's just one of the 60 Christian cemeteries in Rome, yet it's home to roughly a third of all the paintings known to exist in the catacombs.
