The Opera House on Mount Pleasant opened in 1902 as a 1,100-seat theatre and was Tunbridge Wells' grand variety venue throughout the first half of the twentieth century. It declined into a bingo hall after the war and looked set for demolition before the pub chain Wetherspoon converted it in the 1990s — keeping almost all of the Edwardian baroque interior intact.
It is a slightly surreal experience: ordering a pint in the gilded stalls of a working theatre, with the auditorium ceiling painted with Greek muses above you. Worth a look-in even if you are not drinking.
