For hundreds of years lighthouses have shone as literal beacons for sailors, fishermen and ferry passengers providing safe passage ashore. However, with the advancement of sophisticated GPS (Global Positioning Systems), many are now questioning the future of these iconic coastal lights.
Most mariners and fishermen still say that they use the lighthouse as a backup for electronic equipment, although only about 75% of lighthouses in the USA are still operating as navigational aids, federal funding is now almost exclusively limited to the maintenance of the lights.
In Britain, a country whose coastline is protected with hundreds of lighthouses, the last keeper retired in 1998. Now, all British lighthouses are fully automated and monitored from a few central offices.
Germany has been slowly extinguishing its lighthouses over the last decade and keeping them only as historical buildings and not official navigation aids.
