Lighthouse on the seaside pictures desktop wallpaper

A lighthouse is a tall tower-shaped building. Lighting equipment is installed on the top of the tower. The location should be prominent. Note that it should have a specific architectural shape that is easy for ships to distinguish, and it should also become one of the highest points in the port.Since the surface of the earth is curved, the tower must be of sufficient height so that the lights can be seen by distant ships and avoid being obscured by clouds and fog at high altitudes.
