From this bridge you understand the Giudecca better than from anywhere else: it is not one island, but eight islets stitched together by rii (small canals), calli (narrow streets) and bridges. Beneath you runs the rio del Ponte Longo; beyond the fondamenta (canalside walkway), the wide, deep canal once called the Vigano, or Carbonaria, from the barges loaded with coal that moored there.
