Once the official port of the city of Delft, Delfshaven is among the last remaining districts of old Rotterdam that survived World War II. A reconstructed 18th-century windmill stands along a waterfront here lined with gabled houses. The old port district is an open-air museum, interspersed with buzzy cafés and galleries, and is a great place for walking. Amble along the Voorhaven, Achterhaven and Piet Heynsplein and view the trove of historic buildings. The tram and nearby Delfshaven metro station connect Delfshaven to the rest of the city.
