Château de Ronchinne, 19th-century castle in Assesse, Belgium

Château de Ronchinne is a large stone building on a grassy slope above the Crupet valley, between Ivoy, Mont and Crupet. Its yellowish-brown masonry facade has rows of rectangular and dormer windows under a dark grey roof, with a tall conical turret at the left end and two similar turrets on the right roofline. Below the main block, an arcade of rounded arches forms an open colonnade on a lower terrace.

The castle was constructed between 1884 and 1890 for notary Charles-Joseph Logé according to plans by architect Théodore Semaille. It later served as a residence for Princess Clémentine of Belgium, a period that lasted until 1945.

The estate is also known as château de la Poste, a name recalling its 1957 purchase by the Fonds Spécial d'Assistance aux Postiers, which turned it into a holiday centre for postal staff. Princess Clémentine of Belgium, daughter of King Léopold II, lived here from 1912 and had the park felled and replanted to a plan by landscape architect Jules Buyssens.

The property operates as a hotel with 81 rooms distributed across different buildings, including the main castle and the Gardener's House. Visitors will find modern amenities such as heated outdoor pools and saunas available on the grounds for relaxation.

The estate offers specialized accommodation options such as Loft Cubes and elevated cabins that differ from standard hotel rooms. These unconventional lodgings allow guests to experience the grounds in a different way compared to those staying in the classical rooms of the main buildings.
