Herrenhaus Vanselow, Neoclassical manor house in Vanselow, Siedenbrünzow, Germany

Herrenhaus Vanselow is a Neoclassical plastered building on an H-shaped plan, with two and a half storeys above a high basement. Its nine-axis main facade is centred on a three-axis risalit whose pediment carries the coats of arms of Hans Ludwig von Maltzahn and his wife Agnes Alice von Lücken. Inside, bright rooms are arranged around an elliptical spiral staircase.

Vanselow belonged to the Osten castle estate from the 13th century and passed to the von Maltzahn family, documented as feudal owners from 1356. Between 1654 and 1731 it was briefly held by the von Mardefelt, von Winterfeld and von Bohlen families. In the estate's heyday under Hans Ludwig von Maltzahn, Georg Daniel built the new manor from 1870 to 1871; work paused during the Franco-Prussian War and the house was occupied in October 1872.

The coat of arms on the central part of the building represents the von Maltzahn family and their historical presence in the area. These heraldic symbols remain visible today and connect the house to the regional nobility who shaped local life.

The property is now part of an active farm operation and operates as a private residence with limited access. However, the exterior architecture and ornamental details are visible from the road and surrounding area.

The manor's central staircase winds around an elliptical core, a layout that organizes the bright rooms around it. The stucco workers who decorated the facades and interiors likely came from Italy, a detail noted in descriptions of the house.
