The château was built in 1842 by the Marquis Maximilien de Béthune in a style inspired by French Renaissance châteaux.
Ernest Solvay, the founder of the chemical giant Solvay, purchased the estate in 1893.
The park contains an extensive collection of rare tree species, forming a significant arboretum.
The estate's design features a 'miroir d'eau' (water mirror) that creates a reflection of the château architecture.
Artist Jean-Michel Folon selected the restored 17th-century farm building on the property to house his foundation's permanent collection.
The landscape architecture is intentionally designed to shift from formal symmetry near the building to wilder, forest-like conditions further into the park.
The Domaine régional Solvay, located in La Hulpe, features a 19th-century French-style château surrounded by 227 hectares of landscaped parkland. The estate serves as a regional domain of the Walloon Region and is protected as a heritage site. The grounds consist of formal gardens, woodland paths, ponds, and expansive lawns designed with both English and French landscaping influences. The château itself is a private event venue often used for weddings and corporate gatherings, limiting interior access for the general public. Visitors are primarily granted access to the extensive park trails, the arboretum, and the surrounding estate landscapes. The park is home to the Folon Foundation, which displays works by Belgian artist Jean-Michel Folon in a repurposed historic farm building. The estate is located approximately 20 kilometers southeast of Brussels.

Wear sturdy walking shoes to navigate the extensive unpaved woodland paths.
Bring your own water and snacks, as facilities are limited once you move away from the main entrance and the Folon Foundation area.
Check the official website for event-related partial closures, as the grounds can occasionally be restricted for private functions.
Do not attempt to enter the château building unless you are a registered guest for a private event.
The park is generally open daily throughout the year, but the Folon Foundation museum has specific closing days on Mondays.
Stay on marked trails to protect the park's biodiversity; dogs must be kept on a leash at all times.
