Tag: Lighthouse

A lighthouse is a tall structure, usually a tower, built onshore or in the water to guide ships safely along coastlines and warn them of hazards. Lighthouses emit powerful lights through special lenses, helping sailors find their position, avoid dangerous rocks, and enter harbors. These structures often have unique shapes, light patterns, or color markings, making them easy to identify from the sea. Advances in technology have changed their role, but lighthouses remain vital navigation aids and iconic maritime landmarks.
