You might be reminded of other great architectural wonders when considering the sheer space required when housing Zeppelins; Peter Behren’s AEG Turbine factory, the geodesic domes of Buckminster Fuller and, of course, the ego-shattering heights of super-tall skyscrapers in modern Arabian peninsular emirates. Officially the fourth largest structure on earth in terms of volume, this former hanger in Brandenburg, Germany actually counts as the world’s largest structure that does not require load-bearing supports of any kind. Its conception dates to 1996, when the company Cargolifter AG was “floated” on the markets to develop a heavy lift airship, yet the company came crashing down, á la Hindenburg, in the ensuing blue chip crash of the early 21st century. Forced to sell their structure to the kitschy Tropical Islands concept, the building now functions as an amusement park. A trip here is well worth it, if only to bask in the rays of technical grandiosity that arises out of the promise of lost causes.
