History and description

San Petronio Basilica Bologna
Basilica of San Pentronio

The architect Antonio di Vincenzo began construction of the church in 1390. In 1514, Arduino degli Arriguzzi wanted to have the church completely renovated to dwarf St Peter’s Basilica in Rome. He also wanted to change the floor plan to that of a Latin cross. According to legend, the work had to be interrupted by order of Pope Pius IV to start construction of the Archiginnassio, the first seat of the city’s university. Not even the façade was finished (and was never fully completed).

The covering of the nave and apse was completed in 1663. The architect of this work, carried out by Francesco Martini, was Girolamo Rainaldi.

The San Petronio Basilica is 132 metres long, 66 metres wide and has a height of 47 metres. Domenico di Varignana designed the marble covering of the façade and Giacomo Ranuzzi began the work in 1538, but it was never completed. The sculptures on the completed section are the work of Jacopo della Quercia, Amico Aspertini and Alfonso Lombardi.

The central entrance gate, called Porta Magna, is also by Jacopo della Quercia. The pillars depict events from the Old Testament, while the scenes on the architrave are from the New Testament. On the vault, 18 prophets are depicted. The works on the tympanum depict the “Madonna and Child” and “Saints Ambrosio and Petronio”. The central part of the tympanum was made by Amico Aspertini.

The door on the left depicts a “Resurrection” by Alfonso Lombardi and the one on the right a “Descent from the Throne” by Amico Aspertini.

The red brick sides are marked by chapels with pointed turrets. The decorations at the windows were made by several artists, including Antonio di Vincenzo, Francesco di Simone, Domenico da Milano, Pagno di Lapo Portigiani and Antonio di Simone.

The bell tower was built by Giovanni da Brensa between 1481 and 1487.

The San Petronio Museum was opened in 1894.

What to see

The interior consists of three naves. Ten multi-colored pillars support the arches and vaults. The bays of the central nave are square. The side naves are flanked by a total of 22 chapels. Only a few of these chapels have been preserved in their original state.

The tomb against the inside of the façade was made by Zaccaria Zacchi in 1526. The left door was decorated by Francesco da Milano and designed by Alfonso Lombardi, who himself decorated the right door. The relief on the gold door is also by Lombardi.

The San Petronio sundial was designed and made by Gian Domenico Cassini around 1656, after the original sundial had been demolished when the church was enlarged. In the church’s museum, one can see the calculations for making the sundial. At 67.20 metres, it is the longest sundial in the world. In 1775, the iron line was replaced by a version made of brass by astronomer Eustachio Manfredi.

Between chapels 1 and 2, 9 and 10, 13 and 14, and 21 and 22 are 4 stone crosses, which, according to legend, were laid down here by Saint Petronius himself to mark the corners of the city limits.
