National Lighthouse Day is celebrated on August 07, 2020. On August 7, 1789, the US Bureau of Lighthouses was created by the 9th Act of the first Congress which placed lighthouses under federal control. Legislation to declare August 7 the National Lighthouse Day was introduced to Congress in the spring of1988 and signed by President Ronald Reagan on November 5.
A lighthouse is a tower, building, or other type of structure 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. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, safe entries to harbors, and can also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and replacement by modern electronic navigational systems.
The oldest existing lighthouse in the United States is the Sandy Hook Lighthouse in New Jersey (1764), which is still in operation. Often in inaccessible locations, modern lighthouses are more functional and less picturesque; usually they use solar-charged batteries and have a single stationary flashing light sitting on a steel skeleton tower. The last manned lighthouse built in the U.S. was the Charleston Light constructed in 1962. (With material from: Wikipedia)
