The City of Canals
Venice, a city in northeastern Italy, is famous all over the world for its canals. Rather than ordinary streets, much of Venice is laced with waterways. Boats take the place of cars, and the city has earned nicknames like the "City of Canals" and the "Floating City."
A City Built on Water
Venice is not built on solid ground in the usual sense. It sits on a cluster of small islands within a lagoon, a sheltered body of water along the coast. The buildings were constructed on foundations driven down into the soft, muddy ground. The canals weave between these islands, and a large number of bridges connect the different parts of the city on foot. The most important waterway, the Grand Canal, curves through the heart of Venice.
Getting Around by Water
Because Venice is a city of water, transport works differently than almost anywhere else. Cars are banned from most of the city. People and goods move by boat, including water buses and the famous traditional gondolas. This unique character has made Venice one of the most recognisable and visited cities in the world.
