The Grand Canal carves a path through the heart of Venice and serves as the city's main thoroughfare. While water taxis and water buses operate on the waters, the canal winds its way through the center of the city, terminating at the lagoon at one end and the basin, at San Marco square, at the other. Along the way, the jade waters flow past historic structures and sprawling squares, alive with the call of the gondoliers. From the Medieval, Byzantine and Gothic to the Renaissance, Baroque and Neoclassical, the structures that line the Grand Canal form a chronicle of sorts of the city's architectural change across the ages. Romanticized by numerous movies and novels, a gondola ride down the Grand Canal is an essential Venetian experience.
