Between 1925 and 1927, the world-famous bell foundry of Gillett & Johnston in Croydon, England, cast and tuned the Peace Tower Carillon’s 53 bells. The carillon belfry in the Peace Tower is in two sections, located between the Memorial Chamber and the observation deck and clock. The keyboard room, where the player sits, is 45 metres above ground level, situated between the upper and lower sections of the belfry.
The Peace Tower Carillon was inaugurated on July 1, 1927, the 60th anniversary of Confederation. The inauguration ceremony was a major event that marked the first live carillon radio broadcast across Canada and internationally. It is estimated that several million people heard the inaugural concert.
