DETROIT (AP) — The federal government is seeking stewards to care for three historic lighthouses around Michigan.

The Detroit News reports they’re being offered at no cost to eligible state or local governments, nonprofit corporations, historical preservation groups or community development organizations as part of a National Lighthouse Preservation Act program.

One of the lighthouses, the Detroit River Light, has been standing since 1885 in Lake Erie, south of the entrance to the Detroit River. Others are the Minneapolis Shoal Light, which marks the entrance to Little Bay De Noc in Delta County, and the North Manitou Shoal Light.

The lighthouses occupy Great Lakes Public Trust bottomlands owned by Michigan. A steward may use the lighthouses for education, park, recreation, cultural or preservation purposes and must maintain them.
