The Singapore National Stadium or National Stadium is a multi-purpose stadium in Kallang, Singapore. It was completed in late 2013 and officially opened on 30 June 2014, on the site of the former National Stadium, which was closed in 2007 and demolished in 2010.
A centrepiece of the larger Singapore Sports Hub complex, the stadium hosts major association football matches, including the home matches of the Singapore national team.
The stadium features the world's largest retractable domed roof and the configurable seating on the lowest spectator tier to make it the only stadium in the world that is custom-designed to host different sporting events at any given time.
Depending on its configurations, the stadium has a maximum seating capacity of 55,000 for football and rugby, 52,000 for cricket and 50,000 for athletics events/concerts and is the largest stadium in the country in terms of seating capacity. The roof is made out of insulated metal to reflect sunlight.
In addition to Singapore's home games, the stadium also hosts other sporting and cultural events, including the International Champions Cup and the Singapore Sevens. It hosted the 2015 Southeast Asian Games, the 2014 World Club 10s, the 2014 and 2019 Brasil Global Tour, and the 2016 Singapore National Day Parade (NDP).
