Heritage Open Day: Take a backstage guided tour of Stockport Garrick Theatre. Audience members usually only see the public rooms and the auditorium, this is an opportunity to look behind the scenes. Plus a history presentation and photo ops. Have you ever wondered what work goes on backstage to present a play? Why not take the opportunity to find out, take a physical tour of the Garrick. Stockport Garrick was established in 1901 and has occupied the current premises since 1920. It is part of an old mill building on the A6, near to The Hat Museum, and as such it is a veritable rabbit warren.
