About This Tour

A private tour for your group only, through the genuine multi-layer Basilica San Clemente and the real Case Romane del Celio. This is a private tour for your group only. Real stops include the genuine multi-layer Basilica San Clemente and the Case Romane del Celio, Rome's real underground ancient houses.

Basilica San Clemente has earned the nickname "the lasagna church" for its stacked history: the basilica visible today dates to the 12th century, built directly above a 4th-century church that was itself destroyed in the Norman sack of Rome in 1084. Beneath both lie genuine 1st-century Roman structures, uncovered only when 19th-century excavations began tunneling downward in the 1850s.

The deepest level holds a Mithraeum — a cave-like shrine to the Persian-born god Mithras, whose cult drew an exclusively male following, largely soldiers bound by a strict code of discipline. Its altar still shows the god slaying a bull, the central image of Mithraic ritual. By the 4th century, the rise of official Christianity had eclipsed the cult almost entirely, leaving its underground temple sealed beneath the church that eventually replaced it.

Across the hill, the Case Romane del Celio preserves roughly 20 rooms beneath the church of SS. Giovanni e Paolo, built up over four distinct phases between the 2nd and 4th centuries — an apartment block, a wealthy private house, a nymphaeum decorated with marine frescoes, and finally an early Christian space. Tradition holds the martyrs John and Paul once lived here before their execution and burial on the site. Rediscovered in 1887 by Father Germano of St. Stanislaus, the rooms weren't opened as a public museum until 2002, and still hold some of the best-preserved domestic frescoes surviving from ancient Rome.
