The Basilica of San Petronio, dedicated to the patron saint of the city, is the largest church in Bologna. It dominates Piazza Maggiore and, despite being largely unfinished, its imposing dimensions make it the 4th largest church in Italy and the largest Gothic brick church in the world.
In the Basilica of San Petronio, it is impossible not to know what time it is. Instead of a clock, the structure houses the longest sundial in the world. Built by astronomy professor Domenico Cassini, it measures 67 meters and crosses the floor of the church since 1657.
Learn all about the art and history of this church. Afterward, together with your expert guide, you will visit the Archiginnasio Library located next to San Petronio. Here you can discover the history of the oldest university in the world and see the famous Anatomical Theatre.
