Piazza San Domenico, Medieval square near Basilica of San Domenico in Bologna, Italy.

Piazza San Domenico is a square in central Bologna bordered by Via Garibaldi, originally separated from it by a wall. Its surface is paved with river cobbles, as was common in the Middle Ages. Two Gothic monumental arches stand here: the tombs of the glossators Rolandino de' Passeggeri (1305) and Egidio Foscherari (1289). Two columns topped with statues are also present: a Madonna del Rosario by Giulio Cesare Conventi (1632) and a bronze statue of Saint Dominic.

The square emerged around 1250 to accommodate large crowds attending sermons by Dominican friars. It became the religious center of Bologna and maintained this role throughout the centuries.

The square's name comes from the Dominican basilica and convent beside it. In the Middle Ages it served as the open space where crowds gathered to hear the friars' sermons, which is why it was laid out so wide. Two columns with statues stand here: a Madonna del Rosario by Giulio Cesare Conventi, dated 1632, commemorating the end of a plague epidemic, and a bronze statue of Saint Dominic.

The square is easy to reach on foot and close to public transportation stops, restaurants, and cafes. Access is unrestricted and the space is open at all hours.

A third Gothic tomb, of the Muzzarelli family, once stood beside Rolandino de' Passeggeri's tomb but is no longer there. Together with two tombs on Piazza Malpighi, the surviving arches belong to the so-called tombs of the glossators of the Bologna school.
