Books held a very important place in Raoul Warocqué’s life. At the time of his death in 1917, he had a library of over 33,000 volumes reflecting his interest in humanity, science and heritage.

Very little is currently known by specialists or the general public about the majority of Mariemont’s coins and medals. And yet these numismatic collections are immense and varied, spanning the East and West and from Antiquity to the early 20th century.

Mariemont’s collections include textiles, garments and vast quantities of lace that are calling out to be examined. Some of the pieces belonged to Raoul Warocqué’s display collection. Others hail from the wardrobes of the women of the Warocqué family.

Assembled by Raoul Warocqué, with the expert advice of Franz Cumont, Mariemont’s collection of Greek and Roman sculptures is one of the largest in Europe.
