Haus Dahlhausen, Manor estate in Bochum, Germany.

Haus Dahlhausen in Bochum-Hordel is a former knight's estate whose manor house has been a listed building (Denkmal A 112) since 30 October 1989. The grounds now hold two riding halls added by the Göbel family, who have owned the property since 1974 and run a pony farm there.

Haus Dahlhausen was the seat of the von Dahlhausen family, documented from 1321, who held it as a fief of Essen Abbey. In 1546 it passed by marriage to Heinrich von Düngelen; the line died out with Karl Ferdinand Franz Philipp Amalius Freiherr von Düngelen on 21 June 1802. After a long inheritance suit the estate went to the Schragmüller family on 3 July 1809, who sold it to Krupp in 1890 for 580,000 gold marks.

The name Schragmüller, borne by the family that owned the estate from 1809, probably comes from a coal dealer called Fritz-Gustav Müller, who lived on today's Schragmüllerstraße and was nicknamed "der schräge Müller" by neighbours because he grew hemp instead of vegetables in his garden. The street was named after the family in 1926. Since 1974 the Göbel family has run a pony farm here, and the Reit-, Fahr- und Zuchtverein Bochum-Hordel e.V. is based on the grounds.

Haus Dahlhausen lies in Bochum-Hordel, near the Dahlhauser Heide workers' settlement built by Krupp between 1906 and 1915. The grounds are now a pony farm with two riding halls, so visitors should keep to paths and respect riding operations. The Herrenhaus has been a listed monument since 30 October 1989.

The nearby Hannover and Hannibal collieries caused severe mining damage and a falling water table, which shut down the estate's own Grieskamp water mill. Owner Carl-Anton Schragmüller sued the mine owner Krupp over it. In 1890 the house and lands were sold to Krupp for 580,000 gold marks.
