The complex was built by the Augustinian canons around 1700 (from 1690 - 1720). In the course of the Reichsdeputationshauptschluss approx. 1805 the monastery was secularized. In 1818 the Royal Monastery Chamber of Hanover took over the entire complex and ten years later leased the farm to a Rubach family for the first time. 1840 an ancestor of the Görg family (Rittmeister Urban Cleve from Adelebsen) took over the agricultural lease for the first time. He died in 1848 and his son Richard continued the lease for 44 years, then his wife Emilie for another 8 years until her son Oskar was old enough to become a tenant.
The first Görg came to the monastery property in 1932. He was the son-in-law of Richard's brother Herrmann, who as the second born at Gut Grauhof could not become a farm heir and therefore went to West Prussia. Karl Görg ran the farm until 1951. From 1951-1961 Karl-Heinz Görg ran the farm, who died in a plane crash in 1961. From 1961 to 1981 his wife Helga ran the farm first alone and then together with her son Jürgen. Konrad Görg has been the tenant of the Grauhof monastery since 2008.
