The Basilica di San Petronio contains a 67-meter-long meridian line inlaid into the floor, functioning as a massive astronomical instrument.
The facade of San Petronio remains unfinished, with the lower half clad in marble and the upper half showing raw brickwork.
The square sits directly over ancient Roman remains, though the current layout dates specifically to a 13th-century urban renewal project.
The Palazzo del Podestà houses the Voltone del Podestà, which features an acoustic effect allowing two people standing in opposite corners to whisper to each other.
The Neptune Fountain's trident design was used as the inspiration for the Maserati car logo.
Piazza Maggiore serves as the civic and religious heart of Bologna, characterized by its expansive open space surrounded by medieval and Renaissance architecture. The square is dominated by the Basilica di San Petronio, one of the largest brick-built churches in the world. Its western edge is defined by the Palazzo d'Accursio, which has functioned as the city's town hall since the 14th century. The north side features the Palazzo del Podestà, known for its iconic portico and the Voltone del Podestà. A prominent feature is the Fountain of Neptune, located in the adjacent Piazza del Nettuno, which remains physically and functionally integrated with the main square. The area maintains its historical layout from the 13th century and acts as the primary social gathering point for residents. The square is pedestrianized, facilitating heavy foot traffic between the city's historic markets and the university district.

Eating at restaurants directly on the square that lack menus in Italian, as these are often overpriced tourist traps compared to those in the nearby side streets.
Avoid sitting on the fountain edges or historical statues; maintain a respectful volume when entering the Basilica.
