Abstract

A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid for maritime pilots at sea or on inland waterways. The primary purpose of a lighthouse is to serve as a navigational aid and warning beacon for ships at sea. It features an integrated system of heavy foundations, living or service quarters, a central spiral or straight staircase, an upper lantern room, and optical lens arrays designed to withstand extreme wind and wave action. The primary purpose of a lighthouse is to serve as a navigational aid and warning beacon for ships at sea. They help mariners avoid dangerous rocks, reefs, and shallow coastlines, guide vessels safely into harbors, and act as a reliable visual backup when modern electronic navigation systems fail.
