Neutral Moresnet (French pronunciation: ​[mɔʁɛsnɛt], [mɔʁɛsnɛ], German pronunciation: [ˈmɔʁəsnɛt], [ˌmɔʁəsˈnɛt]) 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 after its independence in 1830) and the Kingdom of Prussia. It was 1.5 kilometres (1 mi) wide and five kilometres (3 mi) long, with an area of 360 hectares (900 acres). 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. Its former location is represented presently by the Three-Country Point, the meeting place of the borders of Belgium, Germany, and the Netherlands. During the First World War, Neutral Moresnet was annexed by Germany, although the allies did not recognise the annexation. The armistice between France and Germany in November 1918 forced Germany to withdraw from Belgium and Neutral Moresnet. A year later, the Treaty of Versailles awarded Neutral Moresnet to Belgium, effective 10 January 1920, when the territory was annexed by Belgium to become the municipality of Kelmis. During World War II, Kelmis and the area surrounding was again annexed by Germany and had its name reverted to Moresnet, but the territory was returned to Belgium during 1944.

The Viaduct of Moresnet, also known as the Geul Valley bridge is a railway bridge above and on the southern side of the village of Moresnet, within the municipality of Plombières, close to the three-way Belgian frontier with Germany and the Netherlands. The bridge crosses the Geul Valley. It is a Truss bridge with a maximum height above the valley floor of around 52 metres (171 ft) and a length of 1,107 metres (3,632 ft). Viewed from a horizontal plane the railway line at this point has a gradient of 1.8‰. Viewed from above, approximately a quarter of the bridge is on a slight bend: this has a radius of 1,600 metres (5,249 ft)The Geul Valley bridge was built during the First World War, at a time when, since 1914, Belgium had been under German military occupation. It was built to support the strategic objective of being able to move troops and artillery rapidly between Aachen and Antwerp. More recently, by the 1990s it had fallen into such disrepair that trains crossing it were restricted to a maximum speed of 20 km/h (12 mph). During the early years of the twenty-first century, however, the bridge was extensively reconstructed and restored.
