Recommendable is the "Nieverner Hütte", an iron works on the Fachbacher island Oberau in the Lahn river. It belongs in former times to Nievern and is a recognized industrial monument. The island Oberau was between the 60s and 70s location of the Gustav Fudickar "Schlafwohl" (literally: Sleepwell) upholstery and mattress factory (founded 1885). The Fudickar upholstery and mattress factory built the Fachbacher district "Auf der Oberau" and had patents of special spring mattresses. Today, the building on the island Oberau are used by various small businesses. In the forest of Fachbach were found fossils and the fauna shows many various butterflies, including very rare specimens.
