The Lighthouse Information Center is in the 1907 Fog Signal House, a small brick building east of Old Mackinac Point Lighthouse. Its steam-powered horn steered ships clear from shore in fog and darkness. The Mackinac Island State Park Commission purchased the Fog Signal House, a barn, and the lighthouse in 1960.    German-born John Peter Schmitt and his crew built Old Mackinac Point Lighthouse in 1892. Its light guided ships on the Straits of Mackinac for 66 years. The lighthouse closed in December 1957 after the Mackinac Bridge opened. Old Mackinac Point is listed in the National and State Registers of Historic Places.
