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.
The museum is housed in a cottage (Kate) first built around 1700 and rebuilt in 1804 after a fire. 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. In January 2016, a support association for the operation of the museum was founded.[2]
