Wilhelmstein, Artificial island fortress in Steinhuder Meer, Germany
The star-shaped fortress rises from Lake Steinhude's waters, containing military structures, defensive walls, and barracks spread across multiple connected small islands.
Count Wilhelm of Schaumburg-Lippe commissioned the construction of this military stronghold in 1761, requiring five years to establish the foundation and build the fortifications.
The island's museum exhibits artifacts from its military past, including a model of Germany's first submarine, the Steinhuder Hecht, constructed here in 1772.
Regular boat services depart from Steinhude and Mardorf towns to the island, with the journey taking approximately 25 minutes and tickets costing 10 euros.
During winter months when Lake Steinhude freezes, visitors can reach the fortress by walking across the ice, following designated paths marked by local authorities.
