Селтик Парк
Celtic Park has been used as a venue for Scotland internationals and Cup Finals when Hampden Park has been unavailable. Before the First World War, Celtic Park hosted composite rules shinty-hurling, track and field and the 1897 Track Cycling World Championships. Open-air Masses and First World War recruitment drives were also held there. Celtic Park hosted the opening ceremony of the 2014 Commonwealth Games and has also been used for concerts by the Who and U2.
