The Vaalserberg is also the location of the
tripoint between Germany, Belgium and the Netherlands and so its summit is called the ''
("three country point") in Dutch, Dreiländereck
("three country corner") in German and Trois Frontières
("three borders") or Trois Bornes'' ("three border stones") in French. On the Belgian side, the tripoint borders the region of
Wallonia, including both the regular French-speaking area and the smaller
German-speaking area. The German side falls within the city limits of
Aachen in the state of
North Rhine-Westphalia. Between 1830 and 1919, the summit was a
quadripoint, also bordering
Neutral Moresnet, which is now part of Belgium's German-speaking area. The current Belgian-German border is not the same as the former eastern border of Moresnet with
Prussia but is a little more to the east. Therefore, five different borders came together at this point but never more than four at one time, except possibly between 1917 and 1920, when the border situation was unclear and disputed. The border intersection has made the Vaalserberg a well-known tourist attraction in the Netherlands, with a tower on the Belgian side (; ; ), opened in 1994 to replace the previous tower, built in 1970. It offers a grand panorama of the surrounding landscape. south of the point, a railway crosses the German-Belgian border in the ''''. It is the freight-only railway between
Tongeren and
Aachen. ==Four-borders road==
