Waha Castle, Neoclassical castle in Marche-en-Famenne, Belgium.

Waha Castle is a neoclassical residence in Wallonia with seven window bays arranged across three stories, built from painted brick and bluestone. The main structure is surrounded by outbuildings in a symmetrical layout that housed stables and service areas.

The castle was built in the 16th century and enlarged in the 19th century by architect Wéringer for Lambert Louis le Jeune, whose family lived there from 1845 to 2004. It was listed as protected heritage on 15 January 2002.

The castle was the home of the Lambert Louis le Jeune family from 1845 to 2004, and the property remains a private family residence. The name Waha comes from the old seigneurie of Waha, a village on the hillside above the Famenne. The building is listed as protected heritage in Wallonia.

The castle is a private family home and is not open to visitors; it is seen from the public road and the lawn in front. The building stands on the flank of a hill above the village of Waha, and the ridge path above it gives a wide view over the Famenne and the wooded Ardennes nearby.

The castle's rarest feature is a cast-iron staircase, unusual in a 19th-century Belgian country house. The property stayed with the Lambert Louis le Jeune family from 1845 to 2004, and the building was listed as protected Walloon heritage on 15 January 2002.
