Build a massive cliffside hangar carved directly into the mountain. The entrance should be a huge rectangular opening facing outward over a valley or ocean, large enough for Create: Aeronautics airships. Include a wide stone runway leading inside, multiple maintenance platforms, overhead cranes, storage rooms, balconies overlooking the hangar, industrial details, and a grand command room. Make it feel like a hidden military fortress.
