The Aduard Abbey operated a farm near Terheijl since the Middle Ages. In 1594, it became property of the Province of Groningen. In 1626, it was sold to Caspar van Ewsum, the landdrost of Drenthe who turned it into an estate. The last noble owner was Baron van Westerholt who died in 1852. In 1853, it was sold and the estate was demolished to construct a large farm.
