Fodor's Expert Review Basilica di San Vitale

The octagonal church of San Vitale was built in AD 547, after the Byzantines conquered the city, and its interior shows a strong Byzantine influence. The area behind the altar contains the most famous works, depicting Emperor Justinian and his retinue on one wall, and his wife, Empress Theodora, with her retinue, on the opposite one. Notice how the mosaics seamlessly wrap around the columns and curved arches on the upper sides of the altar area.

School groups can sometimes swamp the site from March through mid-June.
