Château de Bourlémont

The site occupies an isolated promontory at roughly 400 metres above sea level where two streams meet, giving a commanding view over the Meuse valley and surrounding countryside. The plan combines a medieval defensive core of towers and curtain walls with later domestic ranges that close around an interior courtyard, and the grounds include both English‑style parkland and a later formal parterre. The principal silhouette of the east front retains a feudal aspect, dominated by four surviving round towers capped with conical, pepperpot‑style roofs, while historical records note that the castle once carried many more towers in the fourteenth century.

The prominent round towers that define the east elevation date to the thirteenth‑century rebuilding phase. These large circular towers form part of the medieval defensive shell and present the visible masonry of the high medieval period. The bases of several towers were cut with gunports in the sixteenth century to allow cannon to be fired toward the valley, an adaptation that altered their lower courses and introduced later openings into older stonework. The valley‑facing defensive wall likewise shows these later firearms features.

Along the courtyard side the domestic ranges belong mainly to the sixteenth century and form two‑storey living quarters placed against the older fortifications. A south wing from this period includes a covered gallery of round‑arched arcades that frames the courtyard. The north wing in a neo‑Renaissance fashion was added in the nineteenth century and later demolished in the 1950s, so the present ensemble shows both preserved and removed nineteenth‑century elements.

The chapel dedicated to Saint Vincent was fitted in a late fifteenth to early sixteenth‑century Gothic style with flamboyant decoration and contains the tombs of the local lords. Internally the castle preserves several layers of finish from different periods; certain reception rooms keep original ceilings, and the first‑floor salon retains a French‑style ceiling (plafond à la Française) that was specifically protected in the 1977 historic‑monument listing.

The surrounding park reflects two major approaches to garden design. In the nineteenth century an English‑style landscape was installed, with open meadows punctuated by groves, sinuous access drives designed to create changing views, a reorganization of adjacent woodlands, the introduction of new tree species and meandering promenading paths. A lower flower parterre on the east side originally held two heated greenhouses, one of which still survives and was once equipped by a noted glasshouse firm with an early Dutch‑style greenhouse. Between 1935 and 1937 the great east parterre was remade in a formal French manner with boxwood edging, clipped linden trees, large grass squares set off by pyramidal boxwood, new terraces and flowerbeds. At that time the courtyard level was lowered and levelled to increase the apparent height of the south wing and to establish a central flat platform (terre‑plein, meaning a flat central platform) intended to display an aged lime tree.

Scattered around the grounds are ancillary buildings and service installations that served estate life, including a sheepfold, stables, a water tower, a chalet and the spring known as the Samaritaine. The estate today presents a composite of medieval fortifications, post‑medieval domestic additions, nineteenth‑century landscape work, and twentieth‑century formal garden remodeling, with specific façades, roofs and interior decorative elements legally protected and certain nineteenth‑century interventions removed or altered in the mid‑twentieth century.
