Historical Harbour (Porto Palafítico da Carrasqueira). For over two centuries, the harbour built in traditional wooden stakes has served as anchorage for local boats. Over the wharf, stand small buildings which support the fishermen. This palafitte harbour, unique in Europe, lies a small fishing village, Carrasqueira on the left bank of the River Sado.
