Airship hangars are large structures designed to house and maintain airships, which are lighter-than-air vehicles. These hangars provide a controlled environment to protect airships from weather conditions and allow for repairs and inspections. They are typically made of durable materials and can accommodate the size and shape of various airships. The design of airship hangars often includes high ceilings and wide doors to facilitate the movement of these large crafts. Historically, famous airship hangars, such as those used for the Hindenburg, played a crucial role in the development of air travel during the early 20th century.
