guide and warn the ships coming from different directions in the ocean.
A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses. It is used as an aid to navigation for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, ree’s, safe entries to harbors, and can also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined with incoming of modern electronic navigational systems.
