Site of the bloodiest battle fought in Canada (3 July 1814, 878 British and Canadian, 853 US casualties). 

In 2013, ACO learned from the Friends of Lundy’s Lane Battlefield of a proposal to convert the closed Battlefield Public School into a seniors’ home, with a parking lot that will be built on the school’s playing field. When this project is realized the view from the cemetery (which contains the grave of Laura Secord) where the British and Canadian forces deployed their artillery towards the incoming Americans will be obscured. Niagara Falls Municipal Heritage Committee, recommended the school property be designated a Cultural Heritage Landscape but the seniors’ home project was realized - in sight of a ceremonial arch erected in 2015 to commemorate the battle.
