The square is the third-largest in Italy by total surface area.
The 52-arch portico that lines the perimeter was designed to provide shelter for merchants during trade fairs.
The square connects the civic and religious centers of the town, bridging the gap between the Palazzo dei Pio and the Duomo.
The name 'Piazza dei Martiri' commemorates citizens killed by fascist forces during the Second World War.
The proportions of the square were significantly defined during the rule of the Pio family in the 15th and 16th centuries.
Piazza dei Martiri in Carpi is one of the largest squares in Italy, covering approximately 31,000 square meters. Its layout is characterized by a long, rectangular shape lined with a continuous sequence of 52 arches. The square serves as the primary hub of the town, connecting the Palazzo dei Pio and the Cathedral of Santa Maria Assunta. The northern end is dominated by the medieval architecture of the castle complex, while the rest of the square reflects Renaissance urban planning. The open space was originally expanded in the 16th century to host markets and public gatherings. A central green garden area, the Giardino del Teatro, punctuates the otherwise expansive stone pavement. The square remains the functional and social heart of Carpi, hosting major regional events and seasonal markets.
