St. Mark's Basilica was originally the private chapel of the Doge. It became the city's cathedral only in the 1807, as the seat of the Patriarch of Venice.
On a terrace at the top of the Clocktower two great bronze figures, hinged at the waist, strike the hours on a bell.
The Campanile, located in the Piazza San Marco, is one of the most recognizable symbols of the city.
St.Mark's Basilica achieves an Oriental feeling of exoticism, has all the elements of the Venetian style of the Renaissance Art, remains unique, and essentially a product of Italian workers of all sorts.
