A former Solvay family estate with a 1924 rose garden, a walled vegetable garden, an orchard and wet meadows crossed on wooden boardwalks; its chateau, burnt out in 1982, was restored and inaugurated in 2024 to house a physics centre named after Brout, Englert and Lemaitre. It sits on the Green Walk at the edge of the Sonian Forest, far from any tourist route.
