Bologna's fame is closely linked to the reputation and prestige of the Alma Mater Studiorum. Renowned throughout Europe, the University of Bologna has always attracted students from all over the world. Bologna is not a city which attracts mass tourism, but instead it welcomes curious and attentive visitors.Bologna is a city with turrets and porticos which stretch out for kilometres, but it is not ostentatious. Often, the city's most valuable treasures can be found tucked away in magnificent Renaissance palaces, in churches which have been deconsecrated and restored, beneath gateways or inside courtyards.
