The Castle Spectre is a 1797 dramatic romance in five acts by Matthew ＂Monk＂ Lewis. It is a Gothic drama set in medieval Conway, Wales. The Castle Spectre was first performed at the Theatre Royal, Drury Lane, on 14 December 1797. The original cast included William Barrymore, Richard Wroughton, Charles Kemble, John Palmer, James Aickin, William Dowton, Jane Powell and Dorothea Jordan. In a period when very few plays reached ten performances in a season, it was staged forty-seven times before June, when the theatre closed for the summer. The play had a long run also in the following year and remained in the repertoire until the late 1820s, and was revived until the end of the century.
