The theatre was built by John Potter, a carpenter, in 1720. But although the theatre did not have a license, it did not stop Aaron Hill, an actor, to produce 'Henry V' for the theatre in 1726. However, performances at the theatre Royal came to a halt in 1737, as George II enforced the licensing act. Many people were unhappy about this and voiced their displeasure by flooding the theatre, which then led to the closure of the theatre. The theatre was reopened on the 4th of July 1821 with 'The Rivals', under a 99 year lease from the crown.
There have been many different types of plays shown at the Theatre Royal Haymarket over the years including; 'An Ideal Husband' By Oscar Wilde, ' Anthony and Cleopatra' and 'A Streetcar named desire' by Tennessee Williams. As well as many other productions such as: 'When Harry Met Sally' , Victoria Wood's 'Acorn Antiques: the musical' and 'The Rat Pack' featuring the music of Frank Sinatra, Dean Martin and Sammy Davis Junior.
