When indigenous peoples required shelter that was lightweight and structurally sound, fabrics made from animal hides and easily transportable elements were the most viable solution. At the Roman Colosseum, a retractable Velarium provided shading for a more comfortable spectator experience. Now, ethylene tetrafluoroethylene (ETFE) is offering new opportunities.
