The palace of the Prince of Villadorata, which occupies the whole west side, overlooks the square. It was built in 1752, in sandstone, by the famous Spanish architect Vermexio. Vermexio used to sign his works by placing the relief shape of a gecko on the sides of the central cornice. The entrance consists of a wooden door, whose portal is represented by an arch, which has, in the middle, a key with the family crest. On the left side of the façade there is a balcony and a door. On the limit, next to the last door there is a marble plaque, dedicated to those killed in the war. On the right side of the facade, there are two square windows, protected by grilles. On the upper part of the façade, placed at the same height and at the same distance from each other, there are five channels (two have been lost) of rainwater discharge, which have the shape of large shelves, terminating, anteriorly with human viri. The building has no artistic beauty inside, it was rich in furniture, paintings, silverware, precious objects; but it was looted during the last world war. A large central courtyard gives air and light to the interiors; a stone staircase, with two flights, leads to the prince's apartment, which has a very simple structure. From this apartment you enter a large terrace, where were built seats, in stone, now destroyed by time. The walls of the terrace have loopholes, which served to shoot at the pirates. Always from the prince's apartment, but, on the opposite side of the terrace, you enter a small balcony, from which the prince overlooked, to control the work of the fishermen in the warehouse below. This warehouse called "Camperia", has arches, on which were placed sacred images and bowls, intended for offers for the feast of the patron. Inside the warehouse there are the boats used for tuna fishing, the "scieri" and the "muciare", the hooks, (which were used to pull up the fish) and the nets. In a corner of the warehouse there was a small office where the tuna was recorded and weighed.
