It is lovely to stroll under the porticoes that wind for about 40 km around the city center!
In the norther part of the city there is a new international exhibition center planned by Japanese architect Kenzo Tange.

Bologna was an Etruscan town originally called Felsina. In 189 BC it became a Roman colony with the name of Bononia and started to grow in importance until it became an imperial town.
It was damaged by fire under Claudius, then rebuilt and enlarged under Nero, with the addition of some new public buildings. After a period of decadence it acquired new glory under bishop Petronio, who then became patron saint of the city.
From the 11th century Bologna experienced heavy economic and urban growth. It was part of the Lega Lombarda under Federico Barbarossa.
It is believed the university was built here in 1088, the first in Europe.
Dante Alighieri, Petrarca and Boccaccio all were students here.
In the 13th century Bologna was at its height thanks to its academic prestige. Later it was ruled by the Viscontis and the Bentivoglios.
From 1506 till the end of the 18th century it was under papal rule. Between the 16th and 18th century Bologna acquired its present appearance.

During the Napoleonic period the city became the capital of the Repubblica Cispadana and flourished in the cultural, political and economic fields.
For the next 45 years, while papal power was being restored, it played a leading role in the Risorgimento, the Italian movement for independence and unification. Finally, in 1859 the city voted to be annexed to Piedmont and be part of united Italy
