Rione S. Basilio takes its name from the monastery founded in the 11th century, which has now been converted into private homes that still retain much of its ancient architecture.
Along the west side of the building, there is a long monastic corridor covered by lowered barrel vaults, typical of medieval Amalfi architecture. A little further down, the small chapel – probably founded in the same century and remodelled in later periods – consists of a single room covered by a lowered barrel-vaulted ceiling. Above the altar, characterised by a recently-made polychrome marble unit with a statue depicting the Madonna del Carmine and Bambino tra i Santi Andrea and Basilio, is a dome, with a round single lancet window with a small bell on the outside.
From the small churchyard on the southern side of the chapel, there is a panoramic view of the city centre and the rocky faces of the surrounding mountains, on which rise Torre dello Ziro to the east and the Torre di Pogerola to the west.
