Contractors have begun ripping out part of the interior at the Congress Theatre ahead of a major refurbishment.
Some 1,600 seats have been removed from the theatre auditorium and major work is underway to renovate the bars and communal areas.
Downstairs, contractors are getting ready to build a new cafe.
The theatre is expected to be closed for some time while the work is carried out.
It is part of a £44 million scheme to improve the Devonshire Quarter including the theatres and tennis centre.
Herald reporter Annemarie Field went behind the scenes on Tuesday morning to see how the work is progressing.
