Old Fort Erie located in Niagara falls at the rivers edge it originally was not a fort it was built for a trade post and supply storage for the American revolution. In 1803 planning was put forth for a new for Erie just behind the original. Fort Erie is most likely the most formidable fort when it comes to strength of the walls because it was built out of Onondaga Flintstone. The fort was the site of the bloodiest battle in the war of 1812 and in the history of Canada. When the war broke out with the Americans the fort was not fully complete and was much harder to defend. In the end the Americans took the fort and then later abandoned it on June 9 1813 a few days later the British retook it and finished its construction. The fort has battle reenactments and daily historical tours. The entire for is claimed to Be haunted and a such there are ghost walk all of October and well into November.
