Among the surviving elements of the thirteenth-century castle, the Romanesque arch is recognizable, created with Leccese stone, guilloche and decorated with acanthus leaves, plants and animals mounted on the facade of the western side. The tower, built in the mid-sixteenth century by the feudal lords Gattinara Lignani, functioned as defense from the Turks, has small windows with acute arches and a protruding parapet on quatrefoil corbels and culminated with a Guelphic battlement. The main façade, which looks out on Piazza Castello, is embellished with portals with bas-reliefs depicting late baroque floral subjects, the Cross of the Order of the Knights of Malta and the coats of arms of some feudal families of Taurisano. The interiors are fully decorated with distemper. The frescoed vaults of the interior depict the coats of arms of the ducal family and those of families related to them, putti, ladies and floral subjects, dating back to the period between the late 19th century and early 20th century. The floors with remarkable mosaics were made by the Fratelli Peluso Company in the early 20th century. The present building also includes the Chapel of Madonna Consolata, where the splendid eighteenth-century painting depicting St. Alexander can be admired.
