Named in honour of Bologna patron Saint Petronius - 8th bishop of the city from 431 to 450 - the Basilica is the most imposing and important church in Bologna (132m long, 66m wide, 47m high). The construction started in 1390 under the supervision of architect Antonio di Vincenzo. In 1514, Arduino degli Arriguzzi designed a new Latin-cross layout that would overtop St Peter's Church in Rome. According to the legend, Pius IV stopped the construction of this megalomaniac dream and pushed for the construction of the Archiginnasio instead. Even the facade remained incomplete. The central nave covering and the apse shooting, designed by Girolamo Rainaldi and directed by Francesco Martini, were completed only in 1663, while the lower naves were closed by rectilinear walls.
Built in 1470 by Lorenzo da Prato and featuring the most prestigious and oldest functioning organ in the world, the Bologna musical Chapel was once very famous. Another more recent organ (1596) belongs to Baldassarre Malamini, which is also still functioning despite being 400 years old.
In 1894, the Museo di San Petronio designed by T. Azzolini opened.
There are then four stone crosses between the chapels 1-2, 9-10, 13-14, 21-22 that, according to legend, were placed by St Petronio at the corners of the city limit, which was then defined over the following centuries with selenite walls.

Façade - In 1538, Giacomo Ranuzzi started the marble facing designed by Domenico da Varignana, which though remained incomplete. The finished part was decorated with works by sculptors Jacopo della Quercia, Amico Aspertini and Alfonso Lombardi.

Main doorway - Dating back from 1425, the central door is a masterpiece by Jacopo della Quercia. Old Testament's scenes are represented on the pillars as well as 18 prophets on the archivolt. New Testament's scenes are instead represented on the architrave, then a beautiful Madonna and Child and Saint Ambrose and Saint Petronio on the tympanum. The centre of the tympanum's arch is by Amico Aspertini.

Side doors - Alfonso Lombardi’s "Resurrection" on the left door and Amico Aspertini’s "Deposition" on the right one are both noteworthy.

Sides and Bell tower - The sides are made of red bricks arranged to create cuspidate chapels. The ornaments of the first two windows (1393) were designed by Antonio di Vincenzo with the collaboration of Francesco di Simone, Domenico da Milano, Pagno di Lapo Portigiani and Antonio di Simone. The bell tower was designed by Giovanni da Brensa. (1481-1487);

Interior - Even though the interior of the temple was built up over different periods, it has marvellous classical features, far from the Gothic beyond the mountains. It is divided in 3 naves supported by ten pillars with polygon ribs overlooked by arches and vaults: the bays of the main nave have a square shape. In the smaller naves there are twenty-two chapels:

St Abbondio Chapel (I) - formerly dei Dieci di Balia In 1865, Albino Riccardi restored it in the false Gothic style.

St Petronius Meridian In 1656, after Egnazio Danti’s meridian was destroyed during the extension of the church, Gian Domenico Cassini, a teacher in Bologna, invented and created a new one. In order to calculate it, Cassini used some instruments now on show at the Museum. St Petronius’ Meridian is the longest in the world (length: 67.72m, light hole: 27m from the ground, distance between solstices: 56m); its length corresponds to the 600000th part of the earth meridian. In 1775, it was restored by astronomer Eustachio Manfredi, who substituted the iron line with a brass one.
