The Soumagne Tunnel is the longest rail tunnel in Belgium, with a length of 6,505 metres (21,342 ft). Built on the HSL 3 line of the Belgian TGV service for Brussels-Liège-Cologne, the tunnel was completed in 2004. The new line was opened on 12 June 2009. The tunnel links the Liège conurbation with the Herve plateau at a depth of 120 metres (390 ft). Construction and outfitting of the tunnel took place from 2001 to 2005, with the first trains passing through in 2009. The entrances are at Vaux-sous-Chèvremont 50°36′12″N 5°38′14″E and Soumagne 50°36′40″N 5°43′33″E. The tunnel passes under Chaudfontaine, Fléron, Romsée and Ayeneux. The bored section is 5,940 metres (6,500 yd), extended by covered sections of respectively 177 and 388 m. Dozens of geological layers of differing hardness had to be tunnelled through, lime layers needing to be blasted through with dynamite. The tunnel reaches a depth of 127 m in some areas; it has an average ramp height of 1.7%, with a maximum of 2% at the entrance in Soumagne. The free space profile in the tunnel is approximately 69 m2 (740 sq ft), which restricts speeds to 200 km/h (120 mph).

The Fort de Chaudfontaine is one of twelve forts built around Liège, Belgium, in the late 19th century. The overall Fortified Position of Liège was a constituent part of the country's National Redoubt. Fort de Chaudfontaine was built between 1881 and 1884 according to the plans of General Henri Alexis Brialmont. Contrasting with the French forts built in the same era by Raymond Adolphe Séré de Rivières, the fort was built exclusively of unreinforced concrete, a new material, rather than masonry. The fort was heavily bombarded by German artillery in the Battle of Liège. The fort is now used as an adventure park.

The Vesdre (French, French pronunciation: ​[vɛsdʁ]) or Weser (German, German pronunciation: [ˈveːzɐ] (listen)) and Vesder (Dutch, Dutch pronunciation: [ˈvɛzdər]) is a river in Liège Province, eastern Belgium. A few kilometres of the upper reaches also flow through the German municipality Roetgen and form part of the Belgian–German border. The Vesdre's total length is approximately 64 kilometres (40 mi). It is a right tributary to the river Ourthe. Its source lies in the High Fens (Hautes Fagnes, Hohes Venn, Hoge Venen), close to the border with Germany near Monschau. It flows through an artificial lake (Lake Eupen), and then through the towns of Eupen, Verviers, Pepinster and Chaudfontaine. The Vesdre flows into the Ourthe a few kilometres from Liège where the Ourthe in turn flows into the river Meuse. The water of the Vesdre has a high acidity (due to the Hautes Fagnes bogs), which made it very suitable for the textiles industry around Verviers. The Vesdre was the far eastern end of the sillon industriel, the backbone of Walloon industry. Nowadays, the water of the Vesdre is mainly used as drinking water.
