Chicago Harbor Lighthouse (1893). This active lighthouse has had a significant role in the development of Chicago and the U.S. Midwest.

Chicago Harbor Lighthouse (1893), Chicago, Illinois, 2017.

Known as the “Chicago Light,” the Chicago Harbor Lighthouse is an active automated lighthouse dating from 1893.

About one-half mile beyond Navy Pier, the lighthouse stands at the north of the main entrance of the Chicago Harbor in Lake Michigan. The lighthouse has had a significant role in the development of Chicago and the American Midwest and remains an active aid to nautical navigation today.

For more than a century, the U.S. Coast Guard has staffed this lighthouse at the breakwater outside the Chicago Harbor Lock. The lock separates Lake Michigan from the mouth of the Chicago River.

The lock was built in the mid-1930’s and is operated by the U.S. Army Corps of Engineers. The lock is one of the entrances into the Illinois Waterway system at the Great Lakes. The waterway system is a commercial and recreational shipping connection to the Gulf of Mexico by way of the Illinois and Mississippi rivers.

The “Chicago Light” is at that waterway system’s headwaters as it stands in the outer harbor constructed in 1880. The Chicago Light’s conical tower dates from 1893. Twenty-five years later, in 1918, the tower was reconstructed and the base building which contains a fog-signal room and boathouse was added. The architects are not identified.

Through its breakwaters, the main entrance into Chicago Harbor is 580 feet wide. The Chicago Harbor Lighthouse was designated a Chicago Landmark on April 9, 2003. It is the only surviving lighthouse in Chicago and one of two remaining examples in the state of Illinois.

The mouth of the Chicago River at Lake Michigan in Chicago, Illinois, U.S.A. About one mile ahead, the Chicago Harbor Lock, built in the 1930’s, provides the entrance/exit of the Illinois Waterway system at the Great Lakes. The waterway system is a commercial and recreational shipping connection from the Great Lakes to the Gulf of Mexico by way of the Illinois and Mississippi rivers.
