Augusta, Sicily, Italy
Located in Augusta, Sicily, the dirigible hangar's history stretches back to World War I. Today, the Augusta Hangar is the only remaining example of a reinforced concrete airship hangar left in the world. Its 15 reinforced concrete frames rise 31 meters into the air, as do the hangar's unique folding doors.
Preservation authorities have expressed concern at the Hangar's abandonment and subsequent decay and vandalism, and as a result, much effort has been made for its preservation. University of Ferrara contributed to these efforts by scanning the hangar using 3D laser scanning technology, and donating the data to the CyArk archive.
