Fodor's Expert Review Catacombe di San Callisto
Rome
Cemetery
Burial place of several very early popes, this is Rome's oldest and best-preserved underground cemetery. One of the (English-speaking) friars who acts as custodian of the catacomb will guide you through its crypts and galleries, some adorned with early Christian frescoes. Watch out for wrong turns: this catacomb is five stories deep! This site has a large parking area and is favored by big groups; it can get busy.
