Named in honour of Bologna patron saint Petronio - 8th bishop of the city from 431 to 450, the Basilica is the most imposing (a length of 132m, a width of 66m, a height of 47m) and important church in Bologna.  The construction started in 1390 under the supervision of the architect Antonio di Vincenzo. In 1514, Arduino degli Arriguzzi  proposed a new project with a Latin-cross aimed to overtop St Peter's Church in Rome. According to the legend, Pio IV stopped the costruction of this megalomaniac dream and requested to build up the Archiginnasio. Even the facade was left incomplete; the central nave covering and the apses shooting, designed by Girolamo Rainaldi and directed by Francesco Martini, were completed only in 1663; the lower naves were closed by rectilinear walls.
Built in 1470 by Lorenzo da Prato and symbolized by the most prestigious and older functional organ in the world, the bolognese musical Chapel was once very famous. Another organ, more recent (1596), belongs to Baldassarre Malamini and despite its 400 years it is still functional as well.
In 1894, Museo di San Petronio opened with the projet of T. Azzolini.
There are then four crosses of stone between the chapels 1-2, 9-10, 13-14, 21-22 that, according to the legend, St Petronio placed at the perimeter's angles of the town then, in the next centuries, the circle of the selenite walls have been defined.
