Venice itself was built upon a series of islands, sand-banks and land reclaimed from the lagoon. Any sign of those original islands has long since been lost as the city continued to grow and develop as a sea of stone swept over her origins.
Attractions include a visit to The Piazza San Marco including the Basilica and Museo Correr, a cruise down the Grand Canal to spot the important landmark palaces on the way, including the Palazzo Ducale (Doges Palace), as well as the Bridge of Sighs, are definitely worth visiting. The Accademia Gallery with its extensive collection of Venetian paintings and the Rialto Bridge with its surrounding markets are all musts for the Venice visitor.
Venice, the capital of northern Italy Veneto region, is built on more than 100 small islands in a lagoon in the Adriatic Sea. It has no roads, just canals.
