The smaller canals all serve as arteries to the Grand Canal.
The canals were crossed by wooden bridges without steps, and in the case of the wide Grand Canal the bridge at Rialto was carried on boats.
Fine examples of Venetian Byzantine palaces - at least of the façades - are still to be seen on the Grand Canal and in some of the small canals.
Other specimens still in existence are the municipal buildings, Palazzo Loredan and Palazzo Farsetti - if, indeed, these are not to be considered rather as Romanesque - and the splendid Ca' da Mosto, all on the Grand Canal.
This noble pile, with a large and handsome dome, a secondary cupola over the altar, and a striking portal and flight of steps, occupies one of the most conspicuous sites in Venice on the point of land that separates the mouth of the Guidecca from the Grand Canal.
