A moated castle was built after 1200 on the Helweg in front of the Sandforde, an important people and trade route, which was soon followed by a settlement, today's Stadthagen.
The old castle park surrounded by a wall with its winding paths, beautiful groups of trees and a wonderful view of the castle is accessible to visitors. In the park there is still an old so-called half-tower from the time of the fortress.
In the years 1534 to 1544 the current castle was built on the site of the moated castle. Around 1880 it was beautified inside and out. The magnificent early Renaissance building is embellished by stately pediments with semicircular spiers decorated with spheres. The masonry of the castle entrance comes from the old moated castle. Remains of the castle moat can still be seen.
Up until 1607, the castle served the Counts of Schaumburg as their residence. Later as widow's seat or residence of the hereditary prince. The entire castle district has belonged to the state since 1919 and is currently the seat of the tax office.
