Schaumburg Castle is a hilltop castle in Lower Saxony. As the ancestral seat of the Counts of Schaumburg, it shaped the region's history for centuries and remains a landmark of the Schaumburg Land.
History+
The origins of Schaumburg Castle date back to the 12th century, when a hunting lodge presumably stood on this site. Adolf II of Rodenberg had the castle built on the remains of an older complex and subsequently called himself "Edler von Schaumburg." The castle served as the ancestral seat of the Counts of Schaumburg, who played a role in the settlement of the Upper Weser region, East Holstein, and Moravia in the 13th century. From 1517, Schaumburg Castle was primarily used as a dower house. After the main line of the Schaumburg counts died out in 1640, the castle passed to Hesse and became an administrative seat. It fell into disrepair until it was restored as an inn in 1873. Emperor Wilhelm II gifted the castle to the Prince of Schaumburg-Lippe in 1907, who initiated a restoration. Since then, it has been owned by the House of Schaumburg-Lippe.
