About National Lighthouse Day
History & origins
August 7, 1789, is when the First Congress approved legislation for federal support of lighthouses and related aids to navigation. National Lighthouse Day uses that anniversary. The named day is a heritage observance rather than a federal holiday.
Why it matters
The date connects a founding-era statute to the towers still on U.S. coasts, lakes, and rivers — even where GPS has replaced the lamp.
How to celebrate
Visit a lighthouse museum if one is nearby, read a coastal light’s history, or support preservation groups that keep towers standing.
