Solvay Castle

Solvay Castle is a 19th-century mansion built in Flemish Neo-Renaissance style with symmetrically arranged gardens and ornamental sculptures throughout the grounds. The building sits within a 227-hectare estate that includes ponds, woodlands, and several structures scattered across the property.

The estate was built in 1843 for industrialist Ernest Solvay and remained in private family ownership for over a century. In 1972, his grandson donated the entire property to the Belgian State.

The estate now houses the Folon Foundation with more than 500 artworks and serves as a cultural hub for exhibitions and events throughout the grounds. Visitors can experience contemporary art displayed in a former farmhouse that forms part of the larger complex.

The estate is located at Chaussee de Bruxelles 111 and offers free entrance to all visitors with access to three marked walking trails. The grounds are designed to accommodate visitors with reduced mobility and allow easy movement throughout.

A 36-meter tall obelisk topped with a golden sun marks the property boundary and is visible through a straight grass clearing that cuts through the forest. This striking structure serves as an unexpected landmark within the woodland setting.
