Located in the Piazza San Marco, the San Marco Campanile is the bell tower of St Mark's Basilica in Venice, and it is also one of the most recognizable symbols of the city. Towering at a height of almost 99m, this imposing structure stands proudly in a corner of St Mark's Square. Look out for the loggia surrounding the belfry, which originally housed five bells, but only has one surviving bell today. The Marangona, which is the biggest bell, rings to mark the beginning and end of each working day. Also, try to spot a golden weathervane in the form of the archangel Gabriel which sits atop a pyramidal spire. While bell towers might seem rather boring, the sheer grandeur of San Marco Campanile will surely leave you reconsidering that.
