The Duomo is a five-seventeenth-century building, founded on the substratum of the Norman monastery of the eleventh century. On the outside, there is an elegant Baroque façade with a richly ornamented stone portal surmounted by the Bishop's Coat of Arms (17th century) and the seventeenth-century bell tower with a mullioned window. The interior has a basilica, trinavian plan, decorated in a baroque style with stuccos of the eighteenth century, with Abside square ribbed cross.
The altar is very rich, due to its eighteenth-century baroque style. The oil-painted altarpiece of the Madonna Greca or Nera (protector of the village), of Byzantine style, dominates the altar.

The Church of S. Marco was built in 1549 by order of the feudal lord of Isola, Antonio Giovanni Ricca. It was the noble chapel of the Ricca family. Built in poor style sandstone, it has an artistic stone portal all decorated with bas-reliefs and zoomorphic motifs, dominated by the baronial emblem and with a small bell-tower with two lights on which there is a bronze bell from 1613.
Inside we find a monumental sarcophagus, with the remains of the feudal lord, decorated with winged lions and on the bases are reproduced heads of angels and various rural motifs.

The tower Torre di Capo Rizzuto (or Torre Vecchia), in the locality of Capo Rizzuto, is a cylindrical tower, with massive cordonatura stone slabs, built in the sixteenth century, a coastguard against the barbarian incursions. The tower was guarded by a corporal and a soldier, who had the task of watching day and night and report the presence of suspicious ships with special signs: smoke during the day and bonfire at night. Access to the inside of the tower was via a rustic wooden bridge.

The Sanctuary of the Madonna Greca, in Capo Rizzuto, dedicated to the Protectress of Isola Di Capo Rizzuto. Simple and majestic of new construction, the laying of the first stone is dated 1991.
It arises from the idea of creating a multi-purpose social center, which contains a large hall to be used as a place of welcome for pilgrims, meetings for the community, as a space for setting up exhibitions, as a listening room for music and multimedia visions. The surface of the Sanctuary is about 800 square meters which is enhanced by another 200 square meters of balconies.
