This 12th-century church, restored in 1715 after earthquake damage and again in the 1990s, is one of the most beautiful religious buildings in Ravello. The slender bell tower in Arab-Sicilian style rises beside a facade graced by a triple portal. A steep staircase descends on the right, allowing a view of the three high apses, each crowned by a dome and decorated with intertwined arcs. The interior is decorated with 13th- and 14th-century frescoes, mosaics, majolica, stucco work, and bas-reliefs. Particularly beautiful is the 12th-century pergamo by Alfano da Termoli, as well as the 14th-century frescoes in the crypt's apse. The church is usually closed, but you can request a visit at Via San Giovanni del Toro 50.
