Peace Tower, Gothic bell tower on Parliament Hill, Canada

The Peace Tower is a 92-meter-tall Gothic bell tower on Parliament Hill in Ottawa, Canada, featuring four clock faces and 53 bells. Its spire dominates the skyline of the government district and offers views over the city and river.

The present tower replaced the 55-metre Victoria Tower, which burned with most of the Centre Block in 1916; only the Library of Parliament survived. Designed by Jean Omer Marchand and John A. Pearson in the Victorian High Gothic style, it was inaugurated in 1922. John A. Pearson also conceived it as a war memorial, and the Memorial Chamber sits directly above the porte-cochère.

The tower's name honours the peace after the First World War, and it was designed by John A. Pearson as a memorial to Canadians killed in that war. In the Memorial Chamber, eight Books of Remembrance rest in glass cases on seven altars; their pages are turned at 11 a.m. daily so every name is displayed at least once a year.

Free admission tickets for tower visits are distributed at 90 Wellington Street, with guided tours offered throughout the day. Access to the upper levels is only possible at certain times, so arriving early helps avoid waiting.

The clock's mechanical workings were made by the Verdin Company and are set by the National Research Council Time Signal. The flag on the spire is changed daily, and retired flags are mailed free to people on a waiting list that by 2026 stretched over 100 years.
