Theatr Gwynedd was opened in 1975 by the then University College of North Wales (later Bangor University). It was a 344-seat performance space presenting Welsh, English and International theatre as well as concerts, opera, dance, pantomime and children's entertainment. The open end stage functioned with/without proscenium and with/without apron. Raked seating was designed to allow level access to the auditorium for wheelchairs with full front of house facilities. These were enhanced by a gallery for art exhibitions at first floor level. Rectilinear in simple cubic forms, brick faced apart from the fly tower, square openings. Despite local opposition, the theatre closed in November 2008 and was demolished in 2010 to make way for a new performing arts venue, Pontio, which opened in 2015.
