Aachen II

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.

Moresnet is a village and sub-municipality of Plombières in the province of Liège, Wallonia, Belgium. It was originally a German speaking village. Nowadays French is the official language.

Although there were attempts by locals at making it evolve into a fully independent microstate, all of them were thwarted and it remained under double-sovereignty and neutrality until its eventual annexation by Belgium after the First World War. There is a war memorial to German soldiers from Kelmis who were killed during the Franco-Prussian War, located in the Aachener Strasse, and one to inhabitants of Kelmis who were killed in the First and Second World Wars, located in the Kirchplatz (French: Place de l'Église).A small museum in Kelmis, the Museum Vieille Montagne, includes exhibits on Neutral Moresnet.

The siege of Aachen, which lasted from late April or early May until October 1248, was part of the German civil war that began with Pope Gregory IX's proclamation of a crusade against the Emperor Frederick II in 1240. The city of Aachen, which was the traditional coronation site of German kings, supported Frederick II and refused to allow his rival, Count William II of Holland, to enter the city to be crowned. William and his supports besieged the city, forcing it to allow him in, where he was crowned German king. The main primary sources for the siege are the Royal Chronicle of Cologne, the Chronicle of the Monastery of Bloemhof and Matthew of Paris's History of the English.

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.
