Roma - Santa Maria in Trastevere

Santa Maria in Trastevere is one of the oldest churches of Rome. Legends have it that Pope Callixtus I (217-222) had the church built and that it got remodelled later a couple of times. Pope Innocent II (1130-1143) had it rebuilt on its old foundations. Since then It has the present form with three naves, lintelled columns, apse and transept, created largely by materials gleaned from the ruins of the Baths of Caracalla.

The walls of the nartzhex are tiled with spolia. Here are some of spolia. The birds drinking from a chalice, but the barrel and the ship are clearly ancient graffiti.
