The Peacock Theatre is a West End theatre in the City of Westminster, located in Portugal Street, near Aldwych. The 999-seat house is owned by, and comprises part of the London School of Economics and Political Science campus, who utilise the theatre for lectures, public talks, conferences, political speeches and open days. The university has a long lease with London's principal centre for contemporary dance, Sadler's Wells, with whom it has negotiated a deal to bring in dance companies under the banner 'Sadler's Wells in the West End'. The venue often plays host to dance performances, conferences, ballet, pop concerts and award ceremonies. The stage is approximately 36 feet (11 m) by 33 feet (10 m).
Gibbon's Tennis Court became used as a theatre on this site in the 17th century. In 1911, the London Opera House opened on this site, becoming the National Theatre of England, three years later. Neither theatre was successful and the venture was sold, becoming the Stoll Theatre, in 1916.
