The Queen's Theatre is a West End theatre located in Shaftesbury Avenue on the corner of Wardour Street in the City of Westminster. It opened on 8 October 1907 as a twin to the neighbouring Hicks Theatre (now the Gielgud Theatre) which opened ten months earlier. Both theatres were designed by W.G.R. Sprague.
Since April 2004, the theatre has played host to Cameron Mackintosh's production of Les Misérables which transferred after 18 years at the nearby Palace Theatre. The musical celebrated its 20th anniversary at the venue on 8 October 2005 and overtook Cats as the longest running musical of all time a year later on 8 October 2006.
The theatre was Grade II listed by English Heritage in June 1972.
An extensive refurbishment was undertaken in the latter half of 2009 which improved public areas and increased capacity with new seating and boxes reinstated at dress circle level. (Source: Wikipedia)
