Herrenhaus Pronstorf, Manor house and castle in Pronstorf, Germany

Herrenhaus Pronstorf is a manor house and castle in Pronstorf, Schleswig-Holstein, built in red brick with an eleven-axis facade and a mansard roof. The building rises on a high basement floor and is framed by decorative pilasters along its exterior walls.

The estate was first recorded as Pronestorpe in 1307 and served for centuries as a knight's seat in the region. The current building dates from the late 1720s, replacing earlier structures on the property.

The manor house is privately owned and cannot be visited inside; it can only be seen to a limited extent from outside. The estate instead opens its grounds for cultural events: concerts of the Schleswig-Holstein Musik Festival are held here in summer, and a Christmas market takes place in the run-up to Christmas. Since 2008 the former granary gatehouse has served as an exhibition and guest house.

The grounds include farmland and forest, so comfortable shoes are recommended for walking around the estate. A converted granary on site offers both exhibition space and accommodation for those who want to stay longer.

The manor house served as the model for the neo-Baroque manor at neighbouring Gut Rohlstorf, built in 1912. The gatehouse of 1914, one of the largest in Schleswig-Holstein, exceeds the manor house in floor area and volume; it was converted into a hotel from 2008.
