The Rialto Bridge in Venice, Italy is the oldest of the four bridges spanning the Grand Canal. Originally built as a pontoon bridge in 1173, it has been rebuilt several times and now stands as a stone arch bridge connecting the districts of San Marco and San Polo. Designed by Antonio da Ponte, the current bridge was completed in 1591 and features rows of shops on either side. Despite initial skepticism about its engineering, the Rialto Bridge has become an iconic tourist attraction in Venice, drawing visitors to admire its historic charm and picturesque views.
