All were built and maintained by the federal government. All responded to similar changes in our culture and technology. And many were cared for by keepers who had worked at other lighthouses as well. In other respects, however, each lighthouse, including East Brother, has its own unique story to tell. Lighthouses in Central California, past and present.
Lighthouses help mariners in several ways.
Major sea coast lights serve as landfalls for ships arriving from across the ocean. These lighthouses and the smaller lights along the coast and in bays also act as guides for coastal vessels, in some cases warning them of dangerous reefs or shoals. Others mark turning points along the coast or at entrances to bays or harbors. Most also aid mariners as landmarks visible during the day. They are, however, of little help day or night when there is thick fog.
