The Piazza del Duomo ("Cathedral Square") is a wide, walled area at the heart of the city of Pisa, Tuscany, Italy, recognized as one of the main centers for medieval art in the world. Partly paved and partly grassed, it is dominated by four great religious edifices: the Duomo (cathedral), the Campanile (the cathedral's free standing bell tower), the Baptistry and the Camposanto.
