Built in 1114, the cathedral was completely restored by Giuseppe Zimbalo (1659-70).

The secondary facade is typical, more decorative, and opens onto the square. The interior houses remarkable wooden and papier-machè statues. The pictoresque entrance facing onto the square is a fabulous classic gateway designed by Emanuele Manieri.

The bell tower on the east side of the square stands some 70 meters high, comprising 5 stories diminishing in size, crowned by a dome. For visual effect, the Cathedral, erected in 1659 by Giuseppe Zimbalo on the site of the Romanic one, by order of the bishop Pappacoda , presents a very sober main front and a false sidefront, which is opposite to the square.

Inside the cathedral, don't miss the large, imposing paintings by Oronzo Tiso in the main altar apse. The 16th- century "Presepe" by Gabriele Riccardi is enchanting as well, on the altar of the Annunziata.

The backdrop of the square is fascinating thanks to the bishop's palace, restored by Manieri in the 18th century.
On its right is the Seminary Palace, built on the architect Giuseppe Cino's design by order of the bishops Michele and Fabrizio Pignatelli. It is a building of a particular elegance. Characteristic is its facade, which is covered by smooth ashlars and shows a lovely loggia with three arches on the top of the portal.
