Basilica di San Petronio
San Petronio is Bologna's main civic church and one of the largest brick-built churches in the world, though its facade was never finished, leaving the lower half clad in marble and the upper half in bare brick. It was originally planned to outsize even St. Peter's in Rome, a plan the papacy is said to have blocked.
Inside, the nave contains the world's longest meridian line, a sundial-astronomical instrument built into the floor in 1655 by astronomer Gian Domenico Cassini, still used to mark solar noon through a hole in the vault.
Several side chapels hold notable frescoes, including a famous 15th-century depiction of hell by Giovanni da Modena that has drawn controversy and security concerns over the centuries for its depiction of Muhammad.
