The grand Venetian palaces line the Grand Canal whilst gondolas transport passangers around the many wonders.
From Wikipedia: The Grand Canal is a canal in Venice, Italy. It forms one of the major water-traffic corridors in the city. Public transport is provided by water buses (vaporetti) and private water taxis, and many tourists explore the canal by gondola. The banks of the Grand Canal are lined with more than 170 buildings, most of which date to 13th to the 18th century and demonstrate the welfare and art created by the Republic of Venice. The noble venetian families faced huge expenses to show off their richness in suitable palazzos: this contest reveals the citizens’ pride and the deep bond with the lagoon.
