Discover more about Dampfmaschinenhaus „Pumpenhaus / Moschee“

Located on the Neustädter Havelbucht, the Dampfmaschinenhaus is one of Potsdam's most charming and exotic buildings. King Frederick William IV, a romantic and enthusiast of technology, commissioned the building to demonstrate Germany's technological superiority over England. Designed by Ludwig Persius, it was constructed between 1841 and 1843 to resemble a Turkish mosque, with a minaret cleverly concealing the chimney. This unique design earned it the nickname "Potsdam Mosque".The building housed an 81.4-horsepower steam engine built by August Borsig in 1842. This engine pumped water from the Havel River through a 1.8 km pipe to supply the fountains in Sanssouci Park, enabling the Great Fountain to reach a height of 38 meters. The original engine operated for 50 years before being replaced by a more powerful 160-horsepower engine, which was used until 1937.While modern electric pumps now supply water to the fountains, the Dampfmaschinenhaus remains intact as a monument of technical achievement. Since September 1985, it has been a public museum, offering guided tours on weekends and public holidays from May to October. Visitors can marvel at the original Borsig steam engine and explore a permanent exhibition on the building's history and machinery.
