Group Offers Steam Engine Building (Mosque)

To the info page of the venue

The Steam Engine Building on the Neustädter Havelbucht is at once the most charming and one of the most unusual buildings in Potsdam. Frederick William IV, the “Romantic on the throne,” had Ludwig Persius construct it “in the style of Turkish mosques with a minaret as a smokestack” from 1841–43.

The building, which at that time could still be seen from Sanssouci Palace, set a picturesque and architectural accent in Potsdam’s cultural landscape.The steam-driven engine in the “Mosque” (capable of 81.4 hp) went into operation for the first time in October 1842, letting a jet of water in the Great Fountain in front of Sanssouci Palace soar to an impressive height of 38 meters. August Borsig, who was still a young entrepreneur, had built for Prussia the most powerful machine of its time, allowing King Frederick William IV to compete with the technical supremacy of England.

Although water supply to the fountains in Sanssouci Park is now carried out by modern electric pumps, the “Mosque” allows visitors to marvel at technical ingenuity of the past that is still in use – a fascination shared by young and old alike.
