The city
Venice is considered among the most beautiful and best preserved cities in the world, unique in the fact that it is the only city in the world built on water. The city has earned the name of La Serenissima, the most serene, as throughout the city’s remarkably stable history Venice favoured neutrality and peace when possible. Today the city’s peaceful atmosphere is due to the complete absence of cars; boats provide the only means of transport along a system of over one hundred and fifty canals. For those who prefer to explore the city on foot, more than 430 bridges connect the canals and streets or calle together.
