The Low German house is still found in great numbers in the countryside. Most of the existing buildings have, however, changed over the course of the centuries as modifications have been carried out. Those farmhouses that have survived in their original form are mainly to be found in open-air museums like the Detmold_Open-air_Museum (Westfälisches Freilichtmuseum Detmold) in Detmold and the Cloppenburg Museum Village (Museumsdorf Cloppenburg). The latter has set itself the task of uncovering rural historic buildings in Lower Saxony and documenting the most important examples accurately. For the state of Schleswig-Holstein the Schleswig-Holstein Open Air Museum (Schleswig-Holsteinisches Freilichtmuseum) in Kiel-Molfsee is the most important one with its large collection of Fachhallenhäuser and the like. Several of these buildings may also be found at the Kiekeberg Open Air Museum (Freilichtmuseum am Kiekeberg) and the Volksdorf Museum Village (Museumsdorf Volksdorf) in Hamburg; Examples from the eastern part of the Hallenhaus region are displayed in the Schwerin-Mueß Open Air Museum (Freilichtmuseum Schwerin-Mueß).
