Bredebeck Castle (also Bredebeck Estate) was built between 1901 and 1902 by the farmer Hellberg, who had it built in the style of a spacious manor house on a forest clearing near Bergen. The property was initially an agricultural estate and later expanded in the Baroque style. The house is surrounded by a geometrically designed park with avenues, fountains, and ornamental statues – typical of the upper-class landed gentry of the early 20th century.
As early as 1936, the estate was taken over by the German Wehrmacht, when the area around Bredebeck was incorporated into the newly established Bergen-Hohne military training area. After the Second World War, the British armed forces continued to use the castle – primarily as an officers' mess and guest house. It also served as accommodation for members of the British royal family during visiting troops.
Bredebeck Castle was under military ownership until the British withdrawal in 2015. Today, the building is a listed building and is owned by the Federal Agency for Real Estate (BImA). The public is not allowed access, but the site remains preserved as a silent testament to German-British military history and regional estate culture.
For events such as the "Volksradfahren" (People's Cycling Festival) or guided tours (such as those organized by the Bergen Local History Society), there are exceptions where the grounds can be partially cycled or viewed from the outside. Access to the castle is permitted – but only with permission.
