Basilica di San Petronio
Bologna's vast civic basilica anchors Piazza Maggiore. Enter for its unusual scale and meridian line; the painted chapels require a separate visit, while the unfinished façade is easy to appreciate from the square.
Stand back in Piazza Maggiore to see where marble facing stops and brick takes over, then enter the long Gothic nave. Cassini's meridian line crosses the floor, turning the church into an astronomical instrument. The Bolognini Chapel adds vivid medieval painting if you take the separate chapel route.
What to look for
Marble facing gives way to exposed brick high on the façade.
Cassini's meridian line runs across the nave floor.
Giovanni da Modena's frescoes fill the Bolognini Chapel on the separate chapel route.
Useful to know
Start in Piazza Maggiore for a clear view of the incomplete façade before entering.
Check the basilica's official visit information if you want to include the chapel route.
Pair the visit with the nearby Archiginnasio to connect civic and university Bologna.
