Marinehaus, Architectural heritage monument in Berlin-Mitte, Germany.

The Marinehaus is a building with Renaissance Revival architecture located at Am Köllnischen Park in Berlin-Mitte, displaying two floors with rectangular windows and rounded arches along its decorated exterior. The ornamental facade stretches across the entire building and shapes how the place looks from the street.

The Marinehaus was built in 1908/1909 to plans by architect Otto Liesheim for the Berliner Kriegerheim GmbH, at the address Am Köllnischen Park 9 / Brandenburger Ufer 1. After the Kriegerverein became the Marineverein, it served until 1918 as the clubhouse of an imperial navy unit, which gave the building its name. In 1919 the staff of the Volksmarinedivision was quartered here during the November Revolution, commemorated by a plaque on the facade.

The name comes from the Marineverein, the naval association that used the house until 1918. In the GDR era the state-run Konsum cooperative ran a restaurant called Marinehaus here, decorated to match, and a private tenant continued it. A plaque on the facade recalls the staff of the Volksmarinedivision, which was based in the building in 1919.

The Marinehaus stands at the corner of Am Köllnischen Park and Märkisches Ufer in the Luisenstadt, beside the Märkisches Museum. The decorative fountain at the recessed corner has long been out of service. The building is a protected monument; the planned conversion into an extension of the Märkisches Museum, awarded to the Copenhagen office Adept in 2018, had construction slated to begin in 2022, so access may be restricted.

The grand hall on the upper floor was designed like a church interior: a coffered barrel vault, a gallery on three sides, and a stage where a church would have its choir, with a semicircular mural above it. A decorative fountain at the recessed corner of the building has long been out of service.
