ALLIANZ ARENA
THE BIRD's NEST
The National Stadium of China is dubbed the "bird's nest" because of its innovative grid formation. The twig-like structural elements and the bowl-shaped roof are the masterpiece of the project, yet they pose great challenges for technicians and workers to make the building stand on its own feet.
WEMBLEY STADIUM
At almost four times the height of the original, covering twice the area, and with 90,000 seats, the new Wembley Stadium is the largest covered football stadium in the world. The key feature of the new stadium is its partly retractable roof, supported structurally by a spectacular 133-metre-high arch.
