His Majesty's Theatre

His Majesty's Theatre is a West End theatre situated in the Haymarket in the City of Westminster, London. The building, designed by Charles J. Phipps, was constructed in 1897 for the actor-manager Herbert Beerbohm Tree, who established the Royal Academy of Dramatic Art (RADA) at the theatre. In the early decades of the 20th century Tree produced spectacular productions of Shakespeare and other classical works, and the theatre hosted premieres by such playwrights as Bernard Shaw, J. M. Synge and, later, Noël Coward and J. B. Priestley. Since the First World War the wide stage has made the theatre suitable for large-scale musical productions, and His Majesty's has accordingly specialised in hosting musicals. It has been home to record-setting musical theatre runs such as the First World War hit Chu Chin Chow and Andrew Lloyd Webber's The Phantom of the Opera, which has run at His Majesty's since 1986, except during the COVID-19 pandemic theatre closures.

The first theatre on the site was established in 1705 by the architect and playwright John Vanbrugh as the Queen's Theatre. Legitimate drama unaccompanied by music was prohibited by law in all but the two London patent theatres, and the theatre quickly became an opera house. Between 1711 and 1739 more than 25 operas by George Frideric Handel premiered here. The theatre burnt down in 1789, and a new theatre was completed in 1791. Some of Joseph Haydn's series of concerts in London took place at the theatre in the 1790s. In the early 19th century the theatre was home to an opera company (which moved to the Theatre Royal, Covent Garden, in 1847) presenting the first London performances of Mozart's La clemenza di Tito, Così fan tutte and Don Giovanni. It also hosted the ballet of Her Majesty's Theatre in the mid-19th century, before returning to opera with the London premieres of such works as Bizet's Carmen and Wagner's Ring cycle. A third building was constructed in 1868.

The theatre's capacity is 1,216 seats, and the building was Grade II* listed by English Heritage in 1970. LW Theatres has owned the building since 2000. The land beneath it is on a long-term lease from the Crown Estate. The name of the theatre changes with the gender of the monarch. Throughout the reign of Queen Victoria it was called Her Majesty's Theatre, changing to His Majesty's on the accession of Edward VII in 1901. In 1952 the theatre again became Her Majesty's on the accession of Elizabeth II. On 6 May 2023, the name reverted to His Majesty's Theatre following the accession of Charles III the previous year.
