The Middle Keys have experienced a fascinating history, from the time when wreckers plied the Florida Reef to the days of Henry Flagler's audacious overseas railroad.

Once the Overseas Highway opened, travelers could reach Marathon by car and tourism boomed. As more people settled in Marathon, the community grew and flourished. The majesty of the Middle Keys' two Seven Mile Bridges has inspired postcards, paintings, and even movie scenes. Local institutions like the Dolphin Research Center and the Turtle Hospital have also garnered a host of fans.
