Dat ole Hus ("The old house") is a privately run local history museum in the village of Bünzen in the municipality of Aukrug in Schleswig-Holstein.
Its interior rooms portray the living quarters of a farmer from this region from the 18th to the early 20th century.
In 1961 the husband and wife pair, Edith and Werner Hauschildt, established a local history and open air museum in the cottage and its grounds.
In 1970 the couple were granted a licence for a museum cafe serving coffee and Kirschgrütze with whipped cream and hot waffles, baked in an old wood-fired stove.
The municipality initially acquired the property in 2011[1] after the scheduled end of the lease agreement with the Hauschildt family.
