One of Verona's most popular attractions, this 84m-high watchtower provides panoramic views of Verona and nearby mountains. Begun in the 12th century and finished in 1463 – too late to notice invading Venetians – it sports an octagonal bell tower whose two bells retain their ancient names: Rengo once called meetings of the city council, while Marangona warned citizens of fire. A lift whisks you up two-thirds of the way, but you have to walk the last few storeys.
