Le Due Torri
Bologna’s symbol - the Due Torri or Two Towers – was referred to in Dante’s Inferno. Tower of the Asinelli (Torre degli Asinelli) and Tower of the Garisenda (Torre degli Garisenda) were built by patricians in the 12th century.
In the past, the towers were regarded as status symbols. The more powerful the family was, the taller tower was built. Today access to the Garisenda isn't allowed. But there are some great views from the Torre degli Asinelli, which is the tallest one.
