Mazara's central piazza is an attractive space edged by elegant buildings, including the town's 11th-century Cattedrale del San Salvatore , the elegant, two-storey Seminario dei Chierici (dating from 1710) and, on the opposite side of the square, the 18th-century Seminario Vescovile , with an impressive 11-arched portico.
The cathedral was completely rebuilt in the 17th century in the baroque style. Over the portal is a relief from the 16th century of Count Roger trampling a Saracen. Unfortunately, the 1970s office tower on the west side of the square is a visual affront of the highest order – how it managed to get a construction permit beggars belief.
