Basilica di San Petronio
Description
Located off of the main square in the city, and looking, to all intents and purposes, like it's the city's cathedral (it isn't that's a short walk away), this massive church was planned to be larger than St Peter's in Rome, but money and land issues force the Bolognese to scale back their plans, but it's still an incredible building.
