Hämelschenburg Castle

Hämelschenburg is definitely worth a detour. The pond, the park, the horse paddocks, castle tours, drinking coffee and is a good starting point (large car park) for hikes.

Hämelschenburg Castle is a gem of North German architecture and has been completely preserved with the church, farm buildings, park and inventory. Guided tours are available to visit. In them, the unique building and art history is explained and the checkered history of a Lower Saxon noble family is presented authentically. The manor belonging to the castle has been owned by the von Klencke family since 1437 and is managed according to the principle of sustainability. The church in Hämelschenburg is the first free-standing Protestant church building.
