Chiesa Madre SS. Assunta
In the Middle Ages, Petralia Sottana was under the dominion of the Ventimiglia family, whose immense wealth left behind many stunning public works and buildings in the town. The concentration of this architecture is focused in and around the central square of Piazza Umberto I, which is dominated by this 16th-century parish church, an impressive cathedral dedicated to the Madonna of the Assumption. The interior is filled with sculptures from the 14th, 15th, and 16th centuries, including details from Antonello Gangini, a famed Sicilian sculptor who decorated many important churches with his artwork.
