The Two Towers (Due Torri) are a pair of medieval towers in Bologna, Italy. The taller tower is the Torre degli Asinelli, which stands at 97.2 meters (319 feet) tall, while the smaller tower is the Torre Garisenda, which is only 48 meters (157 feet) tall.

Both towers were built in the 12th century and are located in the historic city center of Bologna. The Torre degli Asinelli was originally built as a watchtower and is the tallest leaning tower in Italy, with a lean of about 1.3 meters (4.2 feet). It has 498 steps to reach the top, which offers a panoramic view of the city. The Torre Garisenda was also built as a watchtower, but due to its instability and lean of more than 3 meters (10 feet), it was shortened in the 14th century and is now closed to the public.

The Two Towers are an iconic symbol of Bologna and are included in the UNESCO World Heritage site of the historic center of the city.
