Designed to accommodate a unique collection of work by Hans Arp and Sophie Taeuben-Arp, this museum enjoys dramatic views over the Rhine Valley. The Arp Museum consists out of a main building plus a gallery for special exhibitions. The main building of the museum is situated high above the River Rhein and next to the former Rolandseck rail road station, which now houses the Kumstler-Bahnhof for the Arts. The gallery pavilion for temporary exhibitions has a subterranean corridor. This pavilion is linked by an underpass to the lower level of the old railway station housing a lobby, a shop and a coat room. After passing beneath the Bonn-Mainz rail link, the visitors ascend a single flight of stairs to gain access to a 300 square meter temporary exhibition space.
