Jemeppe Castle, Medieval castle in Marche-en-Famenne, Belgium.

Jemeppe Castle in Hargimont, part of Marche-en-Famenne, consists of a tall square tower with a steep slate roof and red-shuttered windows, a central round turret with a conical black roof, and a lower rectangular wing with dormers. A second round tower with a matching conical roof stands at the right end, and an arched red door sits at the base of the square tower.

The castle was founded in the early 13th century as a fortified residence on the site of a former Roman villa. Successive owners expanded and reinforced the structure over time to meet changing needs and threats.

The name Jemeppe comes from the manor held by the d'Ochain family, whose heiress Catherine de Jemeppe married Raes d'Ans, sieur de Velroux, in 1616. The castle now serves as an events venue and hotel; the political TV programme Het conclaaf was recorded there in 2024, and season 6 of De Verraders for RTL 4 in 2026.

The castle now operates as an events venue and hotel, so the grounds and wings are not freely open to walk-in visitors; check with the venue before planning a stop. It stands in Hargimont, part of Marche-en-Famenne, in the province of Luxembourg. The moats and farmstead that surround the building date from the 17th century.

The 19th-century renovation added ornamental weathervanes to the medieval tower bearing the coat of arms of the de Sauvage-Vercour family. These decorative touches reveal how later owners put their own mark on the ancient structure.
