It is located on the central square in Menden's town center and, together with the neighboring Vincenz Church, is a landmark of the town of Menden.
In addition to the library and cultural office, the reading café is also located there on the first floor and is open at the same times as the library. The listed building has a grand staircase in Art Nouveau style. Of historical importance is the Old Council Hall, which is now used for events and wedding ceremonies and can be visited on request. In summer, the balcony is open. The Dorte Hilleke Library is freely accessible to everyone during opening hours.
