Christianized sites
St. Peter's Basilica, the church of the Vatican, is traditionally located at the burial place of Simon Peter, and most scholars parties agree that the basilica was built on top of a large necropolis on the Vatican Hill. In 1939, an excavation underneath the "grottoes" which lie directly under the current Basilica, uncovered several surviving Roman mausoleums from the necropolis, and in the area directly under the high altar, below the grottoes, the excavators found a structure resembling a temple that they named the "aedicula" (meaning "little temple").
