History and Significance of the Basilica of San Petronio

Construction of the Basilica of San Petronio began in 1390 under the direction of Antonio di Vincenzo, during a time when Bologna sought to assert its independence and religious identity. The initial design envisioned a structure so grand that it might surpass even St. Peter's Basilica in Rome. In 1514, architect Arduino degli Arriguzzi proposed a Latin-cross plan that would have realized that ambition, but legend tells that Pope Pius IV intervened, halting the project to prevent Bologna from overshadowing Rome's spiritual center. Instead, attention was diverted toward building the Archiginnasio, the city's first university building.

Despite the interruption, work continued sporadically, and in 1538 Giacomo Ranuzzi began adding marble panels to the facade - a decoration that remains incomplete to this day. Yet this partial state only adds to its mystique, symbolizing Bologna’s blend of idealism and humility. Inside, the basilica’s three naves open into twenty-two chapels, each richly adorned by artists like Francesco Francia, Lorenzo Costa, Parmigianino, and Donato Credi, creating a living gallery of Renaissance and Baroque devotion.

Things to See and Do in the Basilica of San Petronio

Stepping inside, visitors are immediately struck by the basilica's vast proportions and light filtering through high windows. One of the most remarkable features is the Music Chapel, founded in 1436 and considered the oldest musical institution in Bologna. Its crowning treasure is an organ crafted by Lorenzo da Prato around 1470 - still playable today and reputedly the oldest functioning organ in the world.

Don't miss the Chapel of the Three Wise Men, also known as the Bolognini Chapel, which dazzles with frescoes by Giovanni da Modena. These detailed scenes portray visions of Heaven and Hell, where devils, angels, and saints animate the walls with startling realism - a masterpiece that makes this spot one of the best places to see in Bologna. Another must-see is Cassini's sundial, created in the 17th century by the renowned astronomer Giovanni Domenico Cassini. Measuring an astonishing 67.27 meters, it remains the world's longest sundial and was once used to mark solstices with precision that predated modern instruments.

"This is an amazing structure. Left unfinished on the front facades at the behest of the Pope of the time to avoid bettering the Vatican. Internally,it is vast. Obviously religious in appearance, with private areas to the left, cost to enter, probably important persons memorial areas. I found the time line or something on the floor interesting. It included zodiac symbols, dates( I think) and some type of calibration. If in Bologna, it is a must see...."

"Absolutely jaw dropping cathedral hidden away in plain sight the center of the city! The entry is free, all day, except for when there is a service.The architecture is fantastic, and the interior is squeaky clean. A careful look at the designs will uncover certain symbols that will get you thinking about the story of this place… Can only wonder about all the secrets these walls have heard over the centuries...."

"I'm so glad that I had time to visit and explore the Cathedral Metropolitana di San Pietro while I'm was in Bologna. Located on the top of ViaIndipendenza near the Maggiore Square is a must see. The Cathedral it used to be the main church in the city, which it was rebuilt after the fire in 1141. The bell tower is the second tallest in the city but on my visit it was close. Is worth mentioning to visit the crypt as at the back you can see the ruins of an older church. The church is free to visit..."
