The restored Alexandra Palace Theatre seen from within the projection room.
Originally Opened in 1875, the Theatre was a place of spectacle and delight where audiences of up to 3,000 people were entertained by pantomime, opera, drama and ballet.
A feat of Victorian engineering, the impressive stage machinery was designed so that performers could appear, fly into the air and disappear through the stage.
However, it struggled to compete with the might of the West End and the theatre went on to be used as a cinema, a chapel and the home of music hall stars before a spell as a BBC prop store and workshop.
For 80 years it has been closed to the public, but now a full restoration brings this hidden gem back to its original glory.
