Details: This poster shows a lighthouse on a flat beach. The sky behind the lighthouse is lit up from the setting sun. Some of the small tidepools nearby also reflect the sunset colors.
An aid for navigation and pilotage at sea, a lighthouse is a tower building or framework sending out light from a system of lamps and lenses or, in older times, from a fire. Lighthouses are used to mark dangerous coastlines, hazardous shoals away from the coast, and safe entries to harbors. Lighthouses are often interpreted in dreams as beacons of truth.
