The Château de l’Hermitage is a listed historic monument, and the place where the very first mining company in Northern France was founded. As such, it is also part of the Mining Basin World Heritage Site. While the building itself is private and not open to the public, its outbuildings attract many visitors: the château’s former park, the rows of beech trees planted by Marshal de Cröy in the 18th century, the landscape perspectives created by the long driveways, the remains of the surrounding wall…

A number of signposted itineraries make it easy for families to explore the region, including the Château de l’Hermitage circuit and the Maréchal de Cröy interpretation trail. The GR 121 and 122 offer longer routes that play happily with the border. This is also the case for two cross-border loops, for horse riders and mountain bikers, which make a wide detour into the Belgian part of the forest.
“In search of the ideal garden”, “gardening” the forest, turning it into “a natural history cabinet” – these were the words used by the Duc de Croÿ to describe his project. The château is the center of a plant world he imagined. From the rotunda (its central room), you have a view of eight paths cut through the gardens and continuing into the forest.
The Duke wanted this garden to be organized according to the rhythm of the seasons and the different species he imported. His son Anne-Emmanuel added Anglo-Chinese-inspired perspectives and fabrications, in keeping with the fashion of the day: bridge and pond, wild island, unfinished tower, Chinese bridge…
A fine example of the variety of species imported into the forest by the Duc de Croÿ, who was experimenting with the acclimatization of plants from the ends of the earth, is the 120-year-old sequoia.
The forest, which became a state-owned forest in 1924, covers 720 hectares on both sides of the border. Two-thirds of the forest is French. The dominant tree species are pedunculate oak, beech and ash, but more exotic or original species can be found along the way, such as the purple beech created by Alexandre de Croÿ in the early 18th century.
