Fort Chippawa, 1791
The fortifications which stood on this site were built in 1791 to protect the southern terminus of the Niagara portage road, and serve as a forwarding depot for government supplies. Known also as Fort Welland, the main structure consisted of a log blockhouse surrounded by a stockade. During the War of 1812 several bloody engagements were fought in this vicinity including the bitterly contested Battle of Chippawa, July 5, 1814, and possession of the fort frequently changed hands. A barracks, storehouse, officers' quarters and earthworks were added in 1814-15, but shortly thereafter Fort Chippawa was abandoned and fell into decay.
