Originally called the Empire Palace and opened by Vesta Tilley, music hall entertainer and male impersonator. The 90 feet high tower featured a revolving sphere topped by a statue of Terpsichore, the muse of music and dance. The theatre closed in 1959. Sunderland Council bought it and reopened it in 1960 when the Beatles played during their first UK tour. On 26 April 1976 the 'Carry On' actor Sid James suffered a fatal heart attack on stage during 'The Mating Season'. The theatre is said to be haunted by the ghosts of Vesta Tilley and Molly Moselle, assistant manager to a touring company {Kirkup 2009}. William and T R Milburn architects were commissioned by local man Richard Thornton to create the “Empire Palace”. The empire was opened as a partnership between Richard Thornton, Edward Moss and Oswald Stoll. It is a splendid example of Edwardian architecture.
The building is still in use as an entertainment venue and is now the largest theatre in the region. In 2004 it received a £4.6m refurbishment and now has state of the art equipment as well as a luxurious four level auditorium seating 2250. It is in brilliant condition, surpassing even its newly built grandeur. Recent renovations also revealed the original marble walls and paintings which are proudly on show in its original Edwardian interior.
