Promotional postcard for the Alhambra Theatre, Leicester Square, London. The Alhambra was a popular theatre and music hall located on the east side of Leicester Square, in the West End of London. It was built originally as The Royal Panopticon of Science and Arts opening on 18 March 1854. It was closed after two years and reopened as the Alhambra. The building was demolished in 1936. The name was also adopted by many other British music hall theatres located elsewhere; in Bradford, in Hull and in Glasgow etc. The name comes from association with the Moorish splendour of the Alhambra palace in Granada.
