Fog Signal Station

This building, with its tall chimney and copper roof, was built in 1890, two years before the construction of the Old Mackinaw Point Lighthouse next door, to house a large steam-operated fog signal. In bad weather, the signal's deep booming sound could be heard for miles to guide ships when lighthouse beams could not be seen. The fog signal was finally silenced when the Mackinac Bridge was built in 1957 and fitted with its own fog horn.
