Airship hangars are specialized buildings that are used for sheltering airships during construction, maintenance and storage. Rigid airships always needed to be based in airship hangars because weathering was a serious risk.
The first real airship hangar was built as Hangar “Y” at Chalais Meudon near Paris in 1879 where the engineers Charles Renard and Arthur Constantin Krebs constructed their first airship “La France”. Hangar “Y” is one of the few remaining airship hangars in Europe.
The construction of the first operational rigid airship LZ1 by Count Ferdinand von Zeppelin started in 1899 in a floating hangar on Lake Constance at Manzell today part of Friedrichshafen. The floating hangar turned into the direction of the wind on its own and so it was easier to move the airship into the hangar exactly against the wind.
For the same reason later rotating hangars were built at Biesdorf (today part of Berlin) and at the Nordholz Airbase, to the south of Cuxhaven in Germany. Already before the First World War there were transportable tent constructions as hangars for smaller airships. They were quite common in the US at fairgrounds or exhibitions. The American Melvin Vaniman constructed big tent hangars in France particularly for the French army.
With the construction of Zeppelin LZ1 the era of big rigid airships started in Germany and for this very big airship hangars were necessary. This development started at the Zeppelin plant in Friedrichshafen before the First World War, continued through the war with dozens of hangars for construction of big rigid airships and their operation all over Germany and the occupied territories. In the 1920s and 30's even bigger hangars for the new LZ 129 Hindenburg class airships were built at Friedrichshafen, Frankfurt and at Bartolomeu de Gusmão Airport, Santa Cruz, Rio de Janeiro, Brazil, the only Zeppelin airship hangar of all those built which still exists
