Château de Fayenbois, Renaissance castle in Jupille-sur-Meuse, Belgium.

Château de Fayenbois is the surviving seigneurial residence of a 1625 Mosan-style castle, built of red brick with horizontal limestone bands and a rectangular plan of about 22.5 by 13.5 metres. A round brick tower with a six-sided spire holds the entrance door, and a fixed bridge from 1830 crosses the filled-in moat. The steep slate roof has dormers and a slender corner turret.

In 1619 Prince-Bishop Ferdinand of Bavaria pledged the lordships of Jupille, Bellaire and Queue-du-Bois to Guillaume Fayen, back from Rome; Fayen built the castle from 1625 in a style close to the Curtius palace, and gave it his name. The estate then passed through the Nivolara (1681), Balthasar (1713), van der Heyden de Bilsa (1726), de Rosen (1732), de Thiriart (1818), de la Roussellière (1838) and Sepulchre families. The roof partly collapsed in 1971; Jupille bought the ruin in 1972 for one million Belgian francs, and Liège restored it from 1993 to 2000.

The name Fayenbois comes from Guillaume Fayen, who was granted the seigneuries of Jupille, Bellaire and Queue-du-Bois on 18 November 1619 and gave his name to the castle and the quarter; in Walloon it is Fayin-Bwès. The entrance door sits in a round stair tower with a six-sided spire, and the classicist portal dates from the second half of the 18th century.

The castle now operates as La Clairière de Fayenbois retirement home and is not open for regular visits. Visitors can view the building from the outside and walk around the surrounding grounds.

The 1830 fixed bridge replaced a drawbridge over the filled-in moat, and its plan still echoes the donjon that stood here before 1625. In the park, laid out in 1830 by Amédé de la Rousselière in English landscape style, two small bridges cross the Ruisseau du Fond de Holleux and a rough limestone arch is crowned by the ruin of a neo-Gothic chapel.
