The first room of the museum displays objects from Couperus’s personal life and property, such as his desk and portraits of his relations. All these artefacts are on loan from the Dutch Literary Museum (Letterkundig Museum), which owns the most important collection of Couperiana in the country. This construction guarantees the conservation of unica from Couperus’s life.

In the second and garden rooms, the Museum organises two yearly exhibitions around various themes from Couperus’s work or life. Every exhibition is accompanied by a richly illustrated catalogue which is displayed in the museum in a large page turner, the so-called ‘Couperian wind-mill’.

The Louis Couperus Museum owns a lifesize image of Couperus which was created by the Rotterdam artist Sjoerd Didden. The doll is dressed in a nineteenth century ‘costume de soir’, a gift from Koninklijke Meddens BV, the genteman’s fashion department store where the dandy Couperus used to buy his clothes.
