Jemeppe Castle

The castle occupies a roughly square plan, organized as a four-wing group around a rectangular inner courtyard. A very large quadrangular keep sits in the north‑west corner of the ensemble; its ground-plan dimensions measure about 15 by 11 metres and the wall line rises to roughly 23 metres at the cornice. The tower originally rose five storeys above two cellar levels. Entry to the keep was by a high doorway, and the upper storeys were relatively plain, meant for storage and for sheltering people living on the estate during danger. In the 19th century a roof was added to the keep.

Surrounding the main enclosure were water defences supplied by the Hedrée river. The original arrangement consisted of two concentric moats that were kept full of water; later descriptions refer to a single, wide moat where the double circuit once existed. The main western approach to the inner courtyard was guarded by a single gate reached by a drawbridge. In front of the gate a forecourt and a range of farm buildings once formed the approach to the castle.

The four wings that enclose the courtyard rise to two levels, described in the records as forming a single main floor in height. Three round towers of three storeys each stand at three of the courtyard’s angles, while a smaller square tower stands alongside the great keep, completing the defensive arrangement. Over time narrow slit windows were replaced by wider openings and high roofs with attic spaces were added, reflecting the shift toward residential use. A square farm building to the west of the castle dates to the 17th or 18th century and stands among the ancillary agricultural structures that once served the estate.

Archaeological excavation has revealed that the site’s occupation stretches back to Roman times, with a fortified Roman villa beneath the medieval fabric. The surviving stonework reflects construction phases beginning in the early 1200s and many later interventions, including 18th‑century alterations to openings and roofs and the 19th‑century restoration work across the complex. Today the ensemble shows both restored and altered elements that record its long sequence from Roman occupation, through medieval fortress, to later domestic residence.
