Fort George National Historic Site of Canada

Fort George was a military fortification in Niagara-on-the-Lake, Ontario, Canada. The fort was used by the British Army, the Canadian militia, and the Jeffersonian American Republic Army for a brief period. The fort was mostly destroyed during the War of 1812. The site of the fort has been a National Historic Site of Canada since 1921, and features a reconstruction of Fort George.

The British established Fort George in the 1790s to replace Fort Niagara. Many of its structures were demolished in May 1813, during the Battle of Fort George. After the battle, American forces occupied the fort for seven months before withdrawing in December 1813.
