Belgium–Netherlands border

The Belgium–Netherlands border separates Belgium and the Netherlands and is 450 km (280 mi) long.

Belgium and the Netherlands are part of the Schengen Area. This means there are no permanent border controls at this border, although the controls between Belgium and the Netherlands had been removed well before the Schengen Treaty was signed, as a result of the Benelux Union being signed in 1944 and ratified in 1947.

On the Belgian side, the border is shared by four Flemish provinces (out of the five in the Flemish Region). From west to east: West Flanders, East Flanders, Antwerp and Limburg (Belgium). A small part is shared by the Walloon province of Liège, which also includes the German-speaking East Cantons. On the Dutch side, the border is shared by three provinces: Zeeland, North Brabant and Limburg.

Between Belgian and Dutch Limburg, the border is mostly formed by the Meuse (Maas) river. The other parts of the border is mostly on land. The city of Baarle-Hertog forms a Belgian exclave in the Netherlands. The border is complicated there, with Dutch exclaves inside it.

The eastern end point is the tripoint (together with Germany) at Vaalserberg.
