As tourists gaze up at Michelangelo’s dome in St. Peter’s Basilica, many have no idea that one of Vatican City’s most compelling historic sites is directly beneath their feet: the Vatican Necropolis, also known as the scavi (excavations). This multilevel subterranean area tells the story of Vatican Hill’s ancient Roman suburban beginnings. Take a walk through a 1st-century C.E. necropolis (once a cemetery and mausoleum), 5th-century Christian burial area, the Vatican grottoes, and the original 4th-century church foundation walls.
