Later the former AAOR became the main BT war headquarters for Wales. The distinctive curved glass galleries were stripped out, and new dormitories, air conditioning, canteen etc., were installed in the 1970s but the work was abandoned before completion and the bunker is now disused although the adjacent BT radio site remains in service.
