Brock's Monument, Military memorial in Queenston Heights, Canada

Brock's Monument is a limestone column at Queenston Heights and one of Canada's oldest war memorials. The structure rises about 56 meters and commands views across the landscape above Niagara Falls.

The first monument was erected in 1824 but was damaged by explosives in 1840. The present structure was rebuilt on the same site between 1853 and 1856.

Inside the monument's base, brass plaques carry the epitaphs of Brock and Macdonell, a list of donors and builders, and a tribute to the British, Canadian and First Nations soldiers who died at Queenston Heights. Educational displays outline Brock's life, the battle and the monument's history, including a portion of his limestone arm that fell in 1929.

A 235-step spiral staircase inside the column climbs to a small indoor platform beneath Brock's statue, where porthole windows look out over the Niagara region and Lake Ontario. The monument was closed in 2005 for repairs and reopened in May 2009 after interior walls were relined against condensation and battery-powered emergency lights were installed.

The base of the monument serves as the burial site for Major General Sir Isaac Brock and Lieutenant Colonel John Macdonell. These two military leaders were central figures in the battle, and their entombment at this location makes it a place of honor.
