At the City of Erie, a peninsula, over six miles in length, arches out into the water of Lake Erie forming an expansive natural harbor. French explorers recognized the intrinsic value of the harbor and in 1753 constructed Fort Presque Isle on the mainland near the harbor entrance. The name Presque Isle means “almost an island” in French and referred to the nearby peninsula. From Fort Presque Isle, fur traders could portage their goods fifteen miles to Fort Le Boeuf, located at the upper reaches of the Allegheny River near present-day Waterford, and then float downstream to Pittsburgh and on to Louisiana. Fort Presque Isle and its portage thus became a vital link between the French fur trade network in the Great Lakes and its colony on the Gulf Coast. Control of the Presque Isle region was wrested from the French in 1760 during the French and Indian War, and following the Revolution, the area was incorporated into the State of Pennsylvania in 1792. During the War of 1812, the harbor at Presque Isle was used to construct six warships, including the Brig Niagara, which played a role in Admiral Perry’s convincing victory over the British in the historic Battle of Lake Erie.
The first lighthouse at Erie, and indeed the first American lighthouse on the Great Lakes, was constructed on a mainland bluff in 1818, not far from the site of Fort Presque Isle. For decades, the commercial importance of Erie was directly tied to shipping on the Great Lakes, which increased dramatically in 1824 following the completion of the Erie Canal connecting Buffalo to the Hudson River. The success of New York’s canal prompted Pennsylvania to link Philadelphia to Pittsburgh with a network of canals that opened in 1834. A decade later, the Erie Extension Canal was completed, and the City of Erie became a vital link to cities along the Ohio and Mississippi Rivers.
@milaniet - I couldn't find any reference of a French influence Milanie. The original light tower was only 40 feet, then 17 feet was added in 1896 to direct the projection of the light from the Fresnel Lens out further over the lake. Even though the outside of the tower is square the inside is circular with 78 steps and 16 landings.
