Part of the Nienburg Museum.
The building was erected in 1821 as a representative residence in the classicist style by the Belgian master builder Emanuel Quaet-Faslem (1785-1851) and named after him. The Quaet-Faslem House is owned by the Hoya-Diepholzen Landschaft and serves as the seat of the Nienburg Museum with exhibitions on historical domestic culture. The valuable ceiling wallpaper (French ceiling wallpaper with motifs from antiquity) inside the house is unique in northern Germany. Furthermore there are collection items of supra-regional importance, such as the rococo room (hung with a wallpaper with pictorial motifs), a restored pulpit from 1750 and numerous cast-iron stove plates.
In the Biedermeier garden are the lapidarium (stone collection) and the smoke house: built in 1633 as a small farmer's or cottage house, it originally stood in a small village called Dolldorf in the district of Nienburg. At the beginning of the 1960s, it was faithfully relocated to the museum garden with objects from the area of rural work and culture. The Lower Saxony Asparagus Museum is housed here.
