Marquette Harbor Lighthouse
(continued). "In 1865, the original facility (most likely built of stone and having a detached tower and separate dwelling) was replaced with a 'School House' plan incorporating a 39-foot tower. A new fourth order Fresnel lens could now achieve a focal plane of 70 feet."
"Construction on a wooden fog signal building, outfitted with a single 10 inch steam whistle, was completed in 1874. In 1912, the fog signal was converted to two air-powered diaphones."
"The station was converted to a training post soon after the Coast Guard took control in 1939. The light is still an active aid to navigation. The Marquette Historical Museum is in the process of restoring the light and guided tours are available daily throughout the summer."
