The main waterway of Venice, Italy. Along the natural waterway from St. Mark's Church to St. Kiara's Church, the city is divided into two parts. It is more than 3 kilometers long and 30.70 meters wide, with an average depth of 5 meters. It is connected with many small canals. Municipal transportation mostly passes through these waterways. Venice's houses are uniquely built, and the foundations are submerged in the water, as if they were drilled out of the water. The Venice Grand Canal is known as the Water "Champs Elysees" Avenue in Venice. On both sides of the river, there are various ancient buildings, including Rococo palaces, Moorish houses and, of course, many magnificent Baroque and Gothic churches. During the Renaissance, many great artists left immortal murals and oil paintings in these churches. In addition, stores, markets and banks across the canal have added endless vitality to the waterborne metropolis.
