Flugzeughallen der ehemaligen Fliegerstation Berlin-Friedrichsfelde, Aircraft hangars in Karlshorst, Berlin, Germany.

The Flugzeughallen der ehemaligen Fliegerstation Berlin-Friedrichsfelde are six reinforced-concrete hangars standing north and south of the street Am alten Flugplatz in Berlin-Karlshorst. Each measures 66.50 m by 22.70 m inside and carries three round shell domes of Langlochziegel brick on a 22 m tension ring, with a dome window for light and ventilation and a rotating work platform around it.

Built between 1917 and 1919 during World War I as an aviation facility for the German military, these hangars survived the strict terms of the Treaty of Versailles that banned German military aviation. The structures remained standing through decades of changing ownership and use after the war ended.

The site's name recalls the independent village of Friedrichsfelde, which financed the airfield in 1916 and leased it to the Prussian military for over 45 years. After 1919 the halls housed a border guard squadron and a police flying unit. The northern halls now belong to the Russian Federation.

The site is easily accessible by public transport as it is located in an established Berlin neighborhood. The northern hangars are part of a Russian facility and not open to the public, while the southern structures are integrated into a residential development project.

Each of the three domes per hall had a window at its apex that lit the interior and could also vent it; a rotating work platform was mounted around it. The domes themselves are shell vaults of Langlochziegel (perforated bricks) resting on a 22 m tension ring, a construction the Munich firm Gebrüder Rank built using a French reinforced-concrete patent secured in 1901.
