Lighthouses are buildings designed to aid ships while they navigate the darkness or poor weather. They may be located near a port or docks, on a lone island, on a coast, or near treacherous waters. They contain a tower atop which is placed the lamps and lens. Below may be a structure or house in which lives the lighthouse keeper(s) and necessary repair tools and replacement parts. Lighthouses may be manned, or automated. They are important elements in worlds with stormy weather or mistlands. They are home to sailors, lighthouse keepers, and things that have crawled up from the depths.
Designing Fictional Lighthouses
Lighthouses are an ancient invention, so in worldbuilding they are often used as ruins. Since they are also usually located near a dangerous shoreline, worldbuilders tend to place them in treacherous locations like atop cliffsides, islands or karsts, or on floating rocks. Designing the coast is essential for lighthouses.
Lighthouses may work in combination with a foghorn.
In fantasy worlds, lighthouses are often magically powered.
