Then came the strangest turn in the island's story: it renamed itself after a movie. A 1948 film noir borrowed the island's name for a storm-lashed hotel drama, and the picture became a classic. On June 1, 1952, the Rock Harbor post office made it official — the town would be Key Largo, trading on a fame the island had technically lent the film in the first place. The loop closed again in 1982, when the actual African Queen — the 1912 steam launch from the 1951 river epic, now on the National Register — took up residence in a Key Largo canal, where she still runs visitors today.
The name came long before the fame. Spanish sailors called the island Cayo Largo — "long key" — and the name appears on charts as far back as a 1639 Dutch map. Calusa and Tequesta peoples knew these islands for centuries before that, fishing the flats and moving between the mangrove shores; later came wreckers, salvaging cargo off the reef that would one day make the island famous for gentler reasons.
