The dei Pio’s Castel, an magisterial architectural complex, is the symbol of the city of Carpi. The castle served as the residence of the powerful family from whom it takes its name, who transformed the earlier medieval structure into a refined Renaissance residence. Its façade and the 17th-century Clock Tower are distinctive features of the building, while the central courtyard—with its elegant four-sided portico and round arches showing Bramante's influence—leads visitors to the base of an imposing double staircase. Today, the Castello dei Pio is a multi-museum complex, housing the Musei Civici, which include the Museo del Palazzo, the Museo della Città, and the Museo-Monumento ai Deportati. The latter is a museum dedicated to telling the story of political and racial deportees during World War II.
