Fodor's Expert Review Le Due Torri

Two landmark medieval towers, mentioned by Dante in The Inferno, stand side by side in the compact Piazza di Porta Ravegnana. Once, every family of importance had a tower as a symbol of prestige and power (and as a potential fortress). Now only 24 remain out of nearly 100 that once presided over the city. Torre Garisenda (late 11th century), which tilts 10 feet off perpendicular, was shortened to 157 feet in the 1300s and is now closed to visitors. Torre degli Asinelli (1119) is 318 feet tall and leans 7½ feet. If you're up to a serious physical challenge—and not claustrophobic—you may want to climb its 498 narrow, wooden steps to get the view over Bologna.
