Originally designed by W.G.R. Sprague, St Martin’s Theatre is a pair with the nearby Ambassadors Theatre. First opening in 1916 with musical comedy Houp La!, the theatre was under a 21-year lease with theatre impresario Charles B. Cochran.

Early notable productions included Damaged Goods (1917), A Bill of Divorcement (1920), R.U.R. (1923), starring Basil Rathbone, Meet the Wife (1927), The Green Bay Tree (1938), The Shop at Sly Corner (1945), Guilty Party (1961) and thriller Sleuth (1970).

In 1974, Agatha Christie’s murder mystery The Mousetrap opened at the theatre, after a previous 22 years at the Ambassadors Theatre. Since then, The Mousetrap has become the West End’s longest-running play, exceeding 25,000 performances at St Martin’s Theatre.
