The following information is taken from an information panel on site: Framed by an avenue of protected purple beech trees, the Château de Dieupart presents itself in a significantly altered form today. Nevertheless, it retains an impressive late 17th-century façade on its southwest side, constructed of sandstone and limestone rubble. Some original architectural elements are still recognizable, including tall, round-arched windows on the ground floor and characteristic relieving arches. The history of the site begins in the 15th century, when an ironworks with a blast furnace and forge developed here. In 1889, parts of these old facilities were converted into a power station. Later, the château was repurposed and transformed into a camping and caravanning center. On the heights above Dieupart, there once stood another château, the "Vieux-Jardin" (Old Garden). This medieval structure no longer exists; it was destroyed in 1286 by John I of Brabant. According to legend, some of the limestone blocks used in the Church of Saints-Anges in Dieupart came from this former fortress. Remnants of the structure can still be found in the woods above the southern slope of Dieupart. The Château de Dieupart has been a listed historical monument since December 11, 1986.

Nice place for a coffee stop! The Château also has a campsite with Dutch owners, hence the fact that you will also find bitterballen on the menu of the chateau.

The castle's origins date back to the 11th century. It was first documented in 1155, but the first buildings probably date back to the time of Bishops Henry of Verdun (1075–1091) and Otbert (1091–1119). As one of twelve residences of the Prince-Bishop of Liège, it served to defend the eastern border of the principality.

The Château de Colonster is located in Sart-Tilman, on a rock overlooking the Ourthe valley, on the edge of the city of Liège. The castle and its park have been the property of the University of Liège since 1963. The first references to the castle date back to the fourteenth century. The castle owes its current appearance to Maximilian-Henry of Horion, Count of Horion. The interior of the castle is the work of artist Paul-Joseph Delcloche. In 1966, a fire destroyed a large part of the castle. The restoration and conversion took place under the direction of the architects Henri Lacoste and Jean Opdenberg.
