Sheboygan Lighthouse served as the town’s early shore light on North Point above Lake Michigan, north of the Sheboygan River mouth once known as the Chipewagan. After the site was favorably examined in 1837, the first lighthouse was lit in 1839 as a brick tower attached to a keeper’s dwelling. Its light was improved in 1857 with a fifth-order Fresnel lens, but erosion led to a replacement built farther inland in 1860, with the light mounted on a dwelling roof. As harbor piers, breakwaters, and their lights took over navigation, the bluff light lost importance and was deactivated in 1905. The altered second lighthouse building still survives as a private residence.
