Lyons is a village in Cook County, Illinois, United States. The population was 10,255 at the 2000 census.
Incorporated in 1888, Lyons is steeped in earlier historical roots. In 1673 French Explorer Louis Joliet and Jesuit missionary Father Pierre Marquette left Green Bay, Wisconsin by canoe in search of a western passage to the Pacific. As they traveled into the Spanish controlled area of Louisiana, they realized that the mighty Mississippi drained into the already well known Gulf of Mexico. With winter approaching, they headed north as quickly as possible. To save time, the Pottawatomi Indians who were with them encouraged changing their route to the Illinois River. The short cut led to the Des Plaines River and caused the French travelers to discover “Le Portage.” This half-mile wide area of land connecting the Chicago River and the Des Plaines River, over which they could carry their canoes and supplies, was to become the discovery for which they would both become famous. Later known as the Chicago Portage, this small area became the “Gateway to the West” and was used by thousands of early settlers and traders traveling both east and west. The discovery of “Le Portage” was part of the impetus that led to Chicago becoming a center for the world trade.
Louis Joliet conceived the idea of constructing a canal to connect the two waterways. This idea was to become a reality 200 years later with the opening of the Illinois and Michigan Canal. In time, the part of the I&M Canal that connected the south branch of the Chicago River with the Des Plaines River was replaced with the Chicago Sanitary and Ship Canal, which was completed in 1900. Today, a statue stands in Lyons at the Chicago Portage National Historic Sight just north of Interstate 55 along Harlem Avenue, commemorating this historic National Heritage Corridor which stretches southwest thru La Salle, Illinois.
