Fort George National Historic Site is a historic military structure at Niagara-on-the-Lake, Ontario, that was the scene of several battles during the War of 1812. The fort consists of earthworks and palisades, along with internal structures, including an officer's quarters, blockhouses to accommodate other ranks and their families, and a stone powder magazine, which is the only original building on the site. Opposite the fort, across the Niagara River, stands Fort Niagara in New York, which can be seen from Fort George's ramparts.
