The building is Grade II listed[1] and is the only unsubsidised producing theatre to operate all year round in the United Kingdom.
This theatre was described as 'elegant and splendidly ornamented' and opened with a performance of Elizabeth Inchbald's comedy Everyone Has His Fault (1793) and the musical farce Rosina and was attended by King George III and Queen Charlotte.
The theatre was only used for six weeks each summer when the nearby Eton College was closed and by 1805 it had been sold to a dissenting sect who converted the building into a chapel.
However, local people were unhappy with the loss of their theatre and raised the money to build a new one, this time on Thames Street.
In 1845 a tragedy occurred when 63 year-old Mrs. Sarah Hume fell from the gallery into the pit, breaking her back by falling across the benches and dying almost instantaneously.
Under the management of John Counsell the theatre ran a weekly repertory schedule, changing to fortnightly in the late 1950s and with three-week productions becoming more prevalent in 1963-64.
Under Kenwright's management the repertoire is wide, ranging from the classics and traditional pantomimes to first productions of new work.
