The Piazza - the only urban space big enough to be called a piazza in Venice - is dominated by the Basilica of San Marco and the Doge's Palace , and by the Basilica's campanile (lit. "bell tower") which stands apart from it. The South-East corner by the campanile is open to the lagoon; the rest is surrounded by historic buildings. The square boasts two old, famous and expensive coffee houses, Gran Caff� Quadri and Caff� Florian. It is extremely popular with tourists, photographers and pigeons.
