ISLAMORADA, Fla.—A 150-year-old beacon that helped guide ships through the treacherous Florida Keys coral reefs before GPS, sonar and other technology made it obsolete is shining again as part of a national effort to save historic lighthouses that have dotted the U.S. coast for more than a century.
An Islamorada community group that is spending $6 million to restore and preserve the Alligator Reef Lighthouse turned on its new solar-powered lights on Saturday to remind the public about the effort.
