The Kükelhaus House, together with the Adult Education Centre, marks the entrance to the "Bergenthal Park", which belongs to the former von Dolffssche Hof, a noble farm of the 17th and 18th centuries. The entire estate, which still exists today and consists of a residential house, barn, stables and tea house in the park, was acquired at the end of the 19th century by the merchant Constantin Wilhelm Bergenthal, who thus gave his name to this inner-city park, which is now freely accessible.
The seat of the adult education centre is the former residential house from 1670, which was renovated for this purpose in 1985. The Kükelhaus house was originally the estate's barn and also dates from 1670. The immediately adjoining stable from 1760, which was built later, was converted into a day-care centre for the elderly in 1962.
