The municipal library was founded in 1968 and was located at the "Place du Théâtre" until 1978. In 1979 the library moved to the "Centre Hamilius".

Since 26 September 2008 the library is established at the Cité building, 3, rue Genistre, near the "Place d'Armes". Since that day, the municipal library has become the "Cité-Bibliothèque".

In the new location, the "Cité-Bibliothèque" has not only extended the opening hours, but also increased the collections consisting of: books, audiobooks, films and periodicals in four languages (French, German, English and Luxembourgish) for adults, teenagers and children.

The "Cité-Bibliothèque" is a place of public reading and recreation. The missions of the library are:

• to foster reading and cultural development by offering documents to people of all ages and backgrounds
• to inform and offer easy access to a wide range of media
• to promote contemporary literature and to encourage contact between readers and authors
• to introduce young people and adults to the joy of reading
• to preserve the cultural heritage

The "Cité-Bibliothèque" is an open-access library and all the documents can be consulted in the library and taken out on loan (except for dictionaries and encyclopaedia).
