Basilica dei SS Cosma e Damiano

Basilica in Ancient Rome

Backing onto the Roman Forum, this 6th-century basilica incorporates parts of the Foro di Vespasiano and Tempio di Romolo, visible at the end of the nave. The real reason to visit, though, is to admire the church's vibrant 6th-century apse mosaics, depicting Peter and Paul presenting saints Cosma, Damiano, Theodorus and Pope Felix IV to Christ.

Also worth a look is the 18th-century Neapolitan presepe (nativity scene) in a room off the salmon-pink 17th-century cloister.
