The Rialto Bridge (Ponte di Rialto) is Venice's oldest Grand Canal crossing, a 16th-century stone arch completed in 1591 and one of the city's most recognized landmarks. Designed by Antonio da Ponte (who beat out proposals from Michelangelo and Palladio, among others), the bold single arch replaced an earlier wooden drawbridge that had collapsed twice under the weight of crowds. The bridge spans 48 metres and rises 7.5 metres above the water, with a central portico flanked by two inclined ramps lined with shops. For nearly 700 years before the Accademia Bridge opened in 1854, this was the only way to cross the Grand Canal on foot. The surrounding Rialto district has been Venice's commercial heart since the city's founding. The morning fish market (Pescaria) and produce stalls (Erbaria) still operate on the San Polo side, and the narrow streets near the bridge are packed with bacari (traditional wine bars) and restaurants where locals crowd the counters for cicheti and spritzes. Views from the Rialto Bridge in either direction along the Grand Canal are spectacular, particularly at sunrise before the crowds arrive. The bridge is free and open around the clock, making it an ideal early-morning or late-night destination.
