Construction of the so-called 'French Gate' began at Fort Niagara in 1756. Note the coat of arms - from 1725, the royal coat of arms of France was ordered to be put up over the main gates of towns and forts in New France. The fort itself dates back to the 1720s, and was expanded substantially at the beginning of the Seven Years' War. Several of the original French structures still stand, incorporated within later British and American works. The whole site is now a New York state park.
