Who designed Beijing’s National Stadium known as the Bird’s Nest?

Beijing’s National Stadium, popularly known as the "Bird’s Nest," was designed by the architecture firm Herzog & de Meuron in collaboration with architect Li Xinggang of the China Architectural Design and Research Group.1

The artist and activist Ai Weiwei also served as an artistic adviser for the project. Although Ai was initially involved in the stadium's conception, he later publicly disavowed his role in the project, citing concerns regarding government propaganda and corruption associated with the 2008 Summer Olympic Games.12
