The most famous stadium holding an official capacity of 150,000 spectators is the Rungrado 1st of May Stadium (also widely referred to as the May Day Stadium) located on Rungra Island in Pyongyang, North Korea. Inaugurated on May 1, 1989, this massive multi-purpose architectural marvel spans an area of over 207,000 square meters across eight stories. It is primarily utilized for grand national celebrations, massive political assemblies, athletic track and field matches, and the iconic choreographed Arirang Mass Games, representing an unprecedented scale of structural engineering designed to accommodate enormous crowds.
