The Royal Museum of Mariemont is located in the former royal estate of Mariemont, in Morlanwelz, created in the 16th century by Mary of Hungary and ceded to the Belgian State by its last owner, Raoul Warocqué (1870-1917).
The Warocqué family, who settled in Mariemont in 1798, were a dynasty of industrialists and great lovers of antiques and works of art, who were also involved in the political life of the region.
Today, the collections are very diverse : lace, autographs, decorative objects, Tournai and Chinese porcelain, Gallo-Roman objects from the region, bibliophilia, Egyptian and Far Eastern objects, an arboretum, sculptures (Les Bourgeois de Calais by Rodin, Jef Lambeaux), etc.
