National Lighthouse Day | August 7
(Last Updated On: November 8, 2022)



Observed annually on August 7th, National Lighthouse Day honors the beacon of light that for hundreds of years symbolized safety and security for ships and boats at sea. At one time, the beacon of light could be found across almost all of America’s shorelines.


A lighthouse is described as a tower, building or any other type of structure that is designed to emit light from a system of lamps and lenses and used as an aid to navigation for maritime pilots at sea or on inland waterways. 

A lighthouse serves multiple purposes such as marking dangerous coastlines, hazardous shoals, and reefs providing safe entry to harbors. They also provide aerial guidance. Once lit by open fire and candles, they’re now brightly lit by electric or oil-fueled lamps. However, the number of lighthouses are declining. Maintenance is expensive and modern electrical navigation systems are replacing them.
