The museum celebrates the life and work of the Belle Époque writer Louis Couperus.

The museum was founded in 1996 by Caroline de Westenholz, step daughter of Albert Vogel jr. (1924-1982), a biographer of Couperus, and housed in his former art gallery.

The rooms are stylistically designed to give the impression of how the residence would have appeared in Couperus' day and age.

In addition to the themed exhibitions, the museum organises walking-tours along places of significance to Couperus and his work, such as the houses where characters from his novels lived.

Couperus' desk, manuscripts and personal letters form part of the collection of the Letterkundig Museum.
