Deutschordenskommende Siersdorf

Deutschordenskommende Siersdorf is a Renaissance-style building with four corner towers connected by covered passages and surrounded by a deep water-filled moat that encircles its rectangular layout. The fortified design creates an appearance similar to a small castle, with the church and residential quarters integrated into this compact defensive structure.

Count Wilhelm III donated a church to the Teutonic Order in 1219, establishing a commandry that would operate for nearly 600 years as a regional administrative center. The Order then constructed this fortified compound to consolidate its power and presence in the area.

The Chapel of St. John the Baptist inside served as the spiritual center where the Teutonic Knights gathered to worship and live as a community. The crypt beneath remains a quiet space where visitors can sense the presence of the men who made this their home.

The site can be visited from the outside, and a support association manages the grounds and conducts ongoing preservation work on the structures. It is helpful to check in advance about visiting hours, as access may be limited depending on maintenance activities.

The walls contain an inner layer of straw and clay plaster, demonstrating the medieval building methods used when the structure was first constructed. This mixed-material approach provided both structural strength and insulation, showing how craftsmen solved practical problems with local resources.
