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.

It is located at the foot and on the slope of a hill in the southern part of Liège, located between the rivers Ourthe and Meuse. The lower part involves an area known as Renory and a railway station called Gare d'Angleur and the higher part is located around the roundabout of Sart Tilman where the Liège Science Park is located. Two mansions can be found in the lower part of Angleur : the Chateau Péralta and the Chateau Nagelmackers On the 24th of July 2019, during the July 2019 European heat wave, the hottest temperate ever recorded in Belgium at the time was recorded in Angleur, a temperature of 40.2 °C, however this recorded was again broken the next day in the Flemish town of Begijnendijk.

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 Gramme Institute is a graduate school of engineering part of Haute École HELMo in Liège in Belgium. It was founded in 1906 by Belgian Jesuit Adolphe Renard. It was named "Ecole des Arts et Métiers" after the same school in France. The first promotion came out in 1908 at a time when the studies lasted for 2 years only. The school's mission is the training of highly skilled engineers able to work in all branches of industry. The course period was raised quickly to 3 years and the academic grade of technical engineer was created in 1919. In 1977, the academic grade of industrial engineer was created and studies, now at university level, had a 4-year term. In his hundredth anniversary, recently, the institute has registered its formation in the framework of the Bologna decree granting titles of Bachelor of Science (BS) and Master of Science (MS) degrees at the end of a course period of 5 years. Programmes: "B.S. - Bachelor of Science in Technology & Industrial Science"; "M.S. - Master of Science in Industrial engineering" - Industry & technological management; "M.S. - Master of Science in Industrial engineering" - Sustainable & energetical engineering; Double degree HEC Liège - Gramme (from September 2016): M.S. (180 crédits ECTS) - Masters of Science in Industrial & Business engineering.The school has its own research center, the CRIG, it is named after the inventor of the dynamo, Zenobe Gramme and is part of the ASJEL (Association of higher education institutions in Europe and Lebanon). The alumni are grouped within the association Union Gramme.

The Fort d'Embourg 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 d'Embourg 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 in World War I and again at the opening of World War II. It has been preserved and is operated as a museum.

The municipality consists of the following districts: Beaufays, Chaudfontaine, Embourg, and Vaux-sous-Chèvremont. Some of its best-known enterprises are Galler chocolates, Magotteaux and Chaudfontaine drinking waters. Chaudfontaine was strongly hit by the 2021 European floods.

The Ourthe (French pronunciation: ​[uʁt]; Walloon: Aiwe d' Oûte) is a 165-kilometre (103 mi) long river in the Ardennes in Wallonia (Belgium). It is a right tributary to the river Meuse. The Ourthe is formed at the confluence of the Ourthe Occidentale (Western Ourthe) and the Ourthe Orientale (Eastern Ourthe), west of Houffalize. The source of the Ourthe Occidentale is near Libramont-Chevigny, in the Belgian province Luxembourg. The source of the Ourthe Orientale is near Gouvy, also in the Belgian province Luxembourg, close to the border with Luxembourg. After the confluence of the two Ourthes at Lake Nisramont, the Ourthe flows roughly in north-west and later in northern direction. Near Noiseux it flows for a short distance through the province of Namur. After the municipality of Durbuy it flows into Liège Province. Eventually it flows into the river Meuse in the city of Liège. The most important tributaries of the river Ourthe are the Amblève and the Vesdre. Towns along the Ourthe are Houffalize (Ourthe Orientale), La Roche-en-Ardenne, Hotton, Durbuy, Hamoir and Esneux. Near Hotton, the caves of Hotton are located. In these caves runs a subterranean river which flows in the Ourthe. Near Esneux lies the Roche aux Faucons. This is a vantage point located on a high cliff, above a meander of the Ourthe. In the south, near Marcourt, there is another high cliff where the Hermitage and chapel of Saint-Thibaut is located. Around 1820, William I of the Netherlands demanded the creation of the Ourthe channel. Via the Ourthe, this channel would have connected the Meuse basin with the Moselle basin. Belgium's independence in 1830 put an end to these plans. The main remnant of these works is the unfinished channel tunnel in Bernistap (province of Luxembourg).

Colonster Castle (Château de Colonster) is a castle near Liège in Wallonia, Belgium, sited on a rocky spur in the Ourthe valley. It was first recorded in the 14th century but its present appearance is that of an 18th-century rebuild by Maximilien-Henri de Horion, which turned it from a stronghold into a pleasure palace, with interiors decorated by Paul-Joseph Delcloche. It and its park were acquired in 1963 by the University of Liège.
