An aid for navigation and pilot at sea,
a lighthouse is a tower building or framework sending out light from
a system of lamps and lenses. Lighthouses are used to mark dangerous
coastlines, hazardous shoals, safe entries to harbors and can also assist
in aerial navigation. Because of modern electronic navigational aids,
the number of operational lighthouses has declined.
