Visitors to Niagara Falls can see a variety of monuments and sites dedicated to the War of 1812.
General Brock's Monument:
War of 1812 cemetery (on Lundy's Lane, Niagara Falls)
Laura Secord house (Secord was the woman who warned British troops of the American advance and played a major role in defeating the Yanks).
Unfortunately, there's no great monument to one of the biggest unsung heroes of the war - Tecumseh.
