The sight of a Zeppelin under construction must have been an awe inspiring experience. The hangers that were constructed for this purpose are the largest structures even created and the lightness required for the Zeppelin frames meant that their trusses consisted of sophisticated aluminum struts where each strut was in turn another truss. The overall effect is of incredible complexity and detail, like a gigantic high-tech whale set in a space that resembles a Piranesi engraving of a dungeon with enormous shafts of sunlight lit by dust. Because of their age, this technological look is combined with distinctly archaic elements, such as the gas bags which were made from thousands of cows' stomachs or the scaffolding and ladders which are wooden and rickety.
