The Peace Tower, also known as the Tower of Victory and Peace, is a focal bell and clock tower sitting on the central axis of the Centre Block of the Canadian parliament buildings in Ottawa, Ontario. The present incarnation replaced the 55m Victoria Tower after the latter burned down in 1916, along with most of the Centre Block; only the Library of Parliament survived. It serves as a Canadian icon and had been featured prominently on the Canadian twenty-dollar bill directly adjacent the queen's visage, until the change to polymer.CharacteristicsDesigned by Jean Omer Marchand and John A. Pearson, the tower is a campanile whose height reaches 92.2 m (302 ft 6 in), over which are arranged a multitude of stone carvings, including approximately 370 gargoyles, grotesques, and friezes, keeping with the Victorian High Gothic style of the rest of the parliamentary complex. The walls are of Nepean sandstone and the roof is of reinforced concrete covered with copper.
