The city was occupied by French forces for six years between 1757 and 1763, as part of the conditions of the Second Treaty of Versailles between France and Austria. A large waterworks infrastructure project called the Ganzepoot (goose foot, in Dutch) was constructed in Nieuwpoort in the 19th century to drain the polders and channel water in and around the town and to the North Sea.
The old city centre of Nieuwpoort is located about three kilometers from the coast. Close to the sea, a new tourist centre has developed. Both parts form one contiguous built up area, connected by buildings along the Albert I Laan street and the fishing port. Besides Nieuwpoort proper, two small villages in the Flemish polders are part of the municipality, Sint-Joris and Ramskapelle.
Nieuwpoort is located by the sea. At the coastal line, it borders the municipalities Koksijde at its town Oostduinkerke and Middelkerke at its town Lombardsijde. Because the territory of the town of Ramskapelle expands far inland, Nieuwpoort has a large number of neighbouring towns, most of which are part of 2 large municipalities:
Part of the plot in Cecelia Holland's historical novel The Sea Beggars is laid in Nieuwpoort, in the preliminary states of the Eighty Years' War - with the sailor protagonists feeling oppressed under the harsh Spanish rule and eventually joining the rebellious Watergeuzen.
