Basilica of San Clemente

Rome’s Basilica of San Clemente, often called the ‘lasagna church’ due to its layered history, is a remarkable site that reveals multiple eras of Roman heritage. The 12th-century interior is adorned with intricate Cosmatesque mosaics, some of the finest in Italy. Beneath the surface, visitors can explore two levels of ancient ruins, including a fourth-century basilica with medieval frescoes, a Mithraic temple, and the remnants of an imperial Roman mint. This unique structure offers a vivid journey through centuries of architectural and cultural evolution.
