This conical brick light tower and the attached houses for the keeper and assistant keepers marked Point Iroquois for ships as they passed from Lake Superior into St. Mary's Canal. The larger house and tower were built in 1871 and replaced an earlier wooden tower and house of 1855 (no longer standing). In 1905 an additional house was attached to the mass and the 1871 house was enlarged by raising the roof to accommodate a second floor. Some time between 1911 and 1930, the west house of 1871 was remodeled to accommodate two families, thus providing housing for a total of three lightkeepers at the complex. The walls of the multigabled house are brick and half-timber infilled with stucco. The tapered tower rises nearly fifty-one feet to a lantern deck on which rests the light. A cobblestone wall surrounds the complex. In 1962 the Coast Guard decommissioned the light and soon after transferred the property to the U.S. Forest Service. A section of the lighthouse serves as a visitor information center and museum thanks to the efforts of the Bay Mills/Brimley Historical Research Society.
