Steinhude's pike

Set in the tranquil winter landscape of the Steinhuder Meer, the story of the “Steinhuder Hecht” invites visitors to a fascinating encounter with early engineering and human ingenuity. Conceived in the 18th century by Count Wilhelm of Schaumburg-Lippe and designed by his engineer J. C. Praetorius, the Steinhuder Hecht was the first submarine ever constructed in Germany. It was an ambitious vision that sought to combine sailing above water with tail-fin propulsion beneath it. In 1772, a small prototype is said to have made its maiden dive in the icy waters of the Steinhuder Meer, allegedly carrying eight men for around twelve minutes. Though the outcome of this experiment remains a mystery, its spirit of exploration endures in the history of innovation. During the winter months, when the lake lies calm under a veil of mist and frost, a visit to Wilhelmstein Island offers a unique atmosphere. Inside the historic fortress, visitors can discover sketches and a detailed model of the Steinhuder Hecht, gaining a glimpse into the inventive mind of the era. The contrast between the serene winter landscape and the boldness of this 18th-century invention creates a memorable experience — one that connects the quiet beauty of nature with the daring spirit of discovery.
