Colonster Castle

The castle was first mentioned in the 14th century, but its current appearance is that of an 18th-century reconstruction by Maximilien-Henri de Horion, who transformed it from a fortress into a pleasure palace, with interiors decorated by Paul-Joseph Delcloche. The castle and its park were acquired by the University of Liège in 1963.

Located in an area of 50 hectares, on a rocky promontory, the château de Colonster overlooks the Ourthe valley. This castle, whose history dates back to the 9th century, is an island in the middle of a nature reserve.
Today the Château de Colonster serves as a reception area for the university, and all kinds of symposiums are held there.

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.
