Don Lillo
Richly decorated
The construction of this basilica, dedicated to San Petronio (the patron of Bologna), began in 1392. It was originally planned to be larger than St Peter's in Rome, but a papal ban meant that the facade was never completed. The exterior offers a good example of Gothic architecture, and the interior is richly decorated with a central room at the back where you can see the original plans by the architect Palladio.
