The Royal Lyceum Theatre is a 658-seat theatre in the city of Edinburgh, Scotland, named after the Theatre Royal Lyceum and English Opera House, the residence at the time of legendary Shakespearean actor Henry Irving. It was built in 1883 by architect C. J. Phipps at a cost of £17,000 on behalf of James B. Howard and Fred. W. P. Wyndham, two theatrical managers and performers whose partnership became the renowned Howard & Wyndham Ltd created in 1895 by Michael Simons of Glasgow.
