English: The original Dublin Airport terminal building was designed in the International Style by a team of architects in the Office of Public Works led by Desmond FitzGerald. The design was more or less complete by 1937 and the building was finished in 1940. The design team comprised Kevin Barry, Daithi Hanley, Charles Aliaga Kelly, Dermot O'Toole, and Harry Robson. The viewing balconies which look out over the runways west of the building were open to the public for the first few decades of its life, but were closed eventually for security reasons. Crowds filled the balconies when the Beatles arrived for their first concert in Ireland on 7 November 1963, and when the first Boeing 747 and Concorde flights arrived in Ireland (on 6 March 1971 and 1 October 1983, respectively). The terminal has been restored and is used as offices and departure gates.
