The Solvay Regional Estate in La Hulpe is affectionately called the "Park of a thousand rhododendrons", and is one of the loveliest places for a stroll in the country.Lawns, woods, rhododendron beds, and remarkable varieties of trees enhance some 227 ha. This magnificent wooded park just outside Brussels boasts paths around and over tree-lined hills and ponds with exceptionally rich animal life.It is also home to Béthune castle, built in 1842 using the Loire castles as a model, and its French gardens with decorative sculptures.The castle is not open to visitors.Not far away, Folon’s discreet but clear presence is expressed through the poetry of his art. Like an open book, the Folon Foundation will reveal the different works by this Belgian artist. You will find some of his sculptures spread over the four corners of the property, guarding the estate. The estate, a protected site since 1963, has been listed as a Major Walloon Heritage Site since 1993 and is also part of the Natura 2000 network.
