The Old Stone Chimney is 31-foot-tall, 60-ton masonry chimney originally built as part of a two-story barracks on the site of the French "Fort du Portage," or "Fort Little Niagara," by Daniel de Joncaire in 1750, when the Niagara River and its shores were part of New France on the North American Continent. The chimney was primarily used for cooking and heating, and has been repurposed several times since by British and American interests. During the French and Indian War (1754-63), the barracks was invaded by the British and burned. Only the chimney remained. General Peter Porter incorporated the chimney into his private residence, which was eventually demolished except for the chimney.

Relocated three times (1902,1942, and 2015), the Old Stone Chimney is currently located between the Niagara River and the Niagara Scenic Parkway east of the Adams Slip along the bike path on the river. The new site is accessible from the parkway with a small parking lot. The bike path crosses in front of the chimney and the Niagara River is behind it.
