Venice - Ponte Rialto

The first dry crossing of the Grand Canal was a pontoon bridge built in 1181 by Nicolò Barattieri. It was called the Ponte della Moneta, presumably because of the mint that stood near its eastern entrance.

The development and importance of the Rialto market on the eastern bank increased traffic on the floating bridge. So it was replaced around 1250 by a wooden bridge. This structure had two inclined ramps meeting at a movable central section, that could be raised to allow the passage of tall ships. The connection with the market eventually led to a change of name for the bridge. During the first half of the 15th century two rows of shops were built along the sides of the bridge. The rents brought an income to the State Treasury, which helped maintain the bridge.Maintenance was vital for the timber bridge. It was partly burnt in the revolt led by Bajamonte Tiepolo in 1310. In 1444 it collapsed under the weight of a crowd watching a boat parade and it collapsed again in 1524.

The idea of rebuilding the bridge in stone was first proposed in 1503, and several projects were considered over the following decades. The Venetian Senate appointed three noble provveditori to oversee a design competition for the rebuilding of the bridge, which included Jacopo Foscarini, Alvise Zorzi, and Marcantonio Barbaro of the noble Barbaro family. In 1551 the provveditori requested proposals for the renewal of the Rialto Bridge, and plans were offered by famous architects such as Jacopo Sansovino, Palladio and Vignola, all of which involved a Classical approach with several arches, officially judged inappropriate to the situation. Even Michelangelo was considered to design the bridge.

The present stone bridge, a single span, was designed by Antonio da Ponte, and completed in 1591. It is remarkably similar to the wooden bridge it succeeded. Two inclined ramps lead up to a central portico. On either side of the portico the covered ramps carry rows of shops. The engineering of the bridge was considered so audacious that architect Vincenzo Scamozzi predicted future ruin. The bridge has defied its critics to become one of the architectural icons of Venice.
