Jemeppe Castle, also known as Hargimont Castle (French: Château Jemeppe or Château d'Hargimont), is a castle located in Hargimont in the province of Luxembourg, Belgium. The castle is of medieval origin.
In the Middle Ages, the mansion of Jemeppe consisted of only a few buildings, surrounded by swamps and the river Hedree. This house offered little protection against the ruling families of Namur and Luxembourg, who had been fighting for control of the territory of Durbuy and La Roche since the twelfth century.
At the beginning of the thirteenth century, a fortified house was built, which was later replaced by Jean d'Ochain by a keep protected by moats. Originally, the keep had five floors and two cellars. Access was only possible through a single door on the ground floor. The first two floors served as living quarters, the two floors above were plain and used by the staff, for storage and as protection for the residents of the Jemeppe estate.
The keep remained in the d'Ochain family until 1616, until the heiress, Catherine de Jemeppe, married Raes d'Ans, sieur de Velroux. It is probably Raes d'Ans who, shortly after acquiring the property, extended the fortified tower with the square castle. The double moat and the farm also date from that period. The wings were further modernized in 1739 and 1748, including the addition of more windows.
In 1838 the castle was passed to the Sauvage-Vercour family. Between 1865 and 1875, Adrien de Sauvage-Vercour had extensive renovation works carried out on the castle. Striking are the added gable roofs to the wings, the 'stone crowning' and the steep roof of the keep.
