Built in the 13th century, the castle was remodeled and expanded in the 15th and 16th centuries. From 1978 to 1982, it underwent a comprehensive restoration by Johannes Manderscheid, in close consultation with the historic preservation authorities.

The current project involved improving the thermal insulation of the unheated attic, renewing the lime plaster on the western gable facade (the weather side), refurbishing some windows and shutters, installing a handrail on the bastion staircase, and repairing cracks in the valuable Baroque stucco and the worn 17th-century staircase. The stucco restoration was planned with an experienced conservator and carried out as discreetly as possible.

The critical thermal bridge in the insulation of the top floor ceiling was mitigated, in consultation with an experienced building physicist, by applying an insulating plaster layer to the wall. The project was challenging because the wood preservatives found necessitated protective measures and a black-and-white work zone.

The stair renovation was coordinated and carried out in collaboration with an experienced carpenter. The oak steps, worn down by up to 4 cm, were milled out in the damaged area and replaced with appropriately profiled oak boards. The repair was intentionally left untouched; over time, the repaired areas will fade in color.
