History

It was the site of the "Soldier Key Club", ca. 1910. Earlier names for the island include: "La Parida y su Figulo", "La Parida y su Hijos", "Laurence Key", "Little Soldier Key", "Oswald Island" and "Parida". Current charts show a single key at this location, but many early maps & charts show at least two. In 1989/1990 a Fort Lauderdale Entertainment conglomerate unveiled plans to partner with a day cruise company and begin selling day trips to Soldier Key. This would have required dredging the bay bottom, creating an artificial beach, building tiki huts and concession stands, electrifying and plumbing the island. A group of locals began a grassroots protest, collecting hundreds of signatures of boycotting customers. They held a regatta protest in which twenty or so boats showed up. This was the day the ground war started in the first Gulf War, so their protest action was lost in the news out of Iraq. They ultimately prevailed and the plans for developing Soldier Key were abandoned.
