Neutral Moresnet was a small Belgian–Prussian condominium in western Europe that existed from 1816 to 1920 and was administered jointly by the United Kingdom of the Netherlands, Belgium and the Kingdom of Prussia. It was 1.5km wide and 2.5km long, with an area of 3.5 square kilometres. After 1830, the territory's northernmost border point at Vaalserberg connected it to a quadripoint shared additionally with the Dutch Province of Limburg, the Prussian Rhine Province, and the Belgian Liège Province. That border point's position is currently represented by the Three-Country Point, the meeting place of the borders of Belgium, Germany, and the Netherlands.
