The National Historic Lighthouse Preservation Act is a U.S. law enacted in 2000 to protect and preserve historic lighthouses. This act allows for the transfer of ownership of these lighthouses to non-profit organizations, state or local governments, or other eligible entities. The goal is to ensure that these important maritime structures are maintained and can continue to serve as cultural and historical landmarks. Under this act, lighthouses that are no longer needed for navigation can be preserved for public use, education, and enjoyment. The law also provides a framework for the restoration and maintenance of these sites, helping to safeguard the legacy of important maritime history, including the role of lighthouses in guiding ships safely along coastlines.
