The orangery of the Château de Seneffe is a neo-classical building located in the park of the Château de Seneffe in the province of Hainaut (Belgium)
The orangery of the Château de Seneffe was built in 1782 by the architect Louis Montoyer on behalf of Joseph Depestre (1757-1823), Count of Seneffe and Turnhout, then owner of the château.
It is the subject of a classification as a historical monument, with the castle and the whole site, since December 24, 1958.
The orangery, painted in white, presents a very pure neo-classical style and a plan of perfect symmetry, composed of a central avant-corps of a single bay and two side wings composed of four bays each.
The avant-corps (part of the projecting facade) is made up of two flat pilasters framing a curved French window with transoms and projecting arch key.
These pilasters support a flat entablature surmounted by a molded triangular pediment pierced by an oval oculus.
Each of the side wings is pierced by four high arched windows with braces and ends in a flat pilaster.
The orangery is covered with a hipped roof covered with slates.
