Piazza Dante (also known as Piazza delle Catene, lit. 'Chains' Square') is the main public square in Grosseto, Tuscany, Italy. The piazza is located in the city's historic centre, included within the perimeter of the 16th-century city walls. It is home to the city's main representative buildings, including the St. Lawrence Cathedral, the Palazzo Comunale (City Hall) and the Palazzo Aldobrandeschi, seat of the Province of Grosseto. The northern section of the square is called Piazza Duomo, since it is overlooked by the cathedral's façade.
