The Chiesa Madre, or parish church of Santa Maria Assunta, lies just south of the Palazzo Murat, its green-and-yellow majolica dome topped by a perky cupola visible from just about anywhere in town. Built on the site of the former Benedictine abbey of Saint Vito, the 13th-century Romanesque structure was almost completely rebuilt in 1700. The last piece of the ancient mosaic floor can be seen under glass behind the altar. Note the carved wooden Christ, a masterpiece of devotional religious art, with its bathetic face and bloodied knees, on view before the altar. At the altar is a Byzantine 13th-century painting on wood of Madonna with Child, known popularly as the Black Virgin. A replica is carried to the beach every August 15 to celebrate the Feast of the Assumption. Legend claims that the painting was once stolen by Saracen pirates, who, fleeing in a raging storm, heard from a voice on high saying, "Posa, posa" (Put it down, put it down). When they placed the image on the beach
near the church, the storm calmed, as did the Saracens. Embedded over the doorway of the church's bell tower, set across the tiny piazza, is a medieval bas-relief of fishes, a fox, and a pistrice (the mythical half-dragon, half-dog sea monster). This is one of the few relics of the medieval abbey of Saint Vito. The Oratorio houses historic statues from the Sacristy; renovations to the Crypt have unearthed 1st-century Roman columns.
