Vaimõisa (German: Waddemois) is a village in Märjamaa Parish, Rapla County in western Estonia.[1]
Vaimõisa as a landed estate has existed at least since 1494,[2] but the first manor house was probably destroyed during the Livonian War.[3] The first estate was established by a bailiff serving under Bishopric of Ösel-Wiek.[3] Throughout the centuries, the estate belonged to several Baltic German families, including the Farensbach, Flemming, Nascakin, Wetter-Rosenthal, Baranoff and Wilcken family.[2] Among more illustrious owners are Gustave Rosenthal, who fought in the American Revolutionary War, and General H. Rautsmann, who taught Carl Gustaf Emil Mannerheim, can be mentioned.[4]
The construction of the main building which still exists today started in 1792 and was finished in 1818. It is a comparatively well-preserved manor house, with some interior features, such as original doors, stucco decoration, fireplaces and parquet floors, surviving to this day.[3]
Apart from the main building, the manor park and some outbuildings, including a Gothic Revival smithy, remain.[2]
