National Stadium - Beijing

This architectural wonder was built for the 2008 Summer Olympics and is aptly nicknamed the 'Bird's Nest'. The inner seating bowl is encompassed by a seemingly random mesh of crisscrossing beams, designed to disguise those that support the stadium's retractable roof, leading to its nest-like appearance. With space enough to accommodate a whopping 91,000 fans, the stadium now hosts a variety of events, from live performances and concerts, to sports and much more. The vast arena has quickly become a symbol of Beijing's cosmopolitan spirit and modern outlook.
