Pigeon Key Foundation

Welcome to the Pigeon Key Foundation & Marine Science Center. Here, Henry Flagler saw the potential for the Keys and opened the islands of the Florida Keys to the world. What was once called Flagler’s Folly has become Flagler’s Legend. Please come inside and see where history, marine science, architecture and education come together on one small 5-acre island!

Pigeon Key is located 2.2 miles due west of Marathon in the Florida Keys. Located approximately 45 miles from Key West and 100 miles southwest of Miami, the island connects to Marathon via the Old Seven Mile Bridge built by Henry Flagler for his Florida East Coast Railway. Pigeon Key is operated by the Pigeon Key Foundation, a non-profit organization dedicated to preserving the history and environment of the Florida Keys through education and research.
