The term 'THEATRE GALLERY' is a combination of two words, 'THEATRE' and 'GALLERY'. THEATRE refers to a building or outdoor area in which plays, musicals, operas, ballets, and other performances are presented. A GALLERY is an area within a building, usually a museum or art GALLERY, where works of art are displayed. The combination of these two words creates a space that combines the elements of both THEATRE and art. An example of this would be an AMPHITHEATRE, which is an open-air THEATRE with seating arranged in tiers around a central stage.
