If you walk down to the end of Margaret Street in Key West today, you’ll find a bustling waterfront filled with the smell of saltwater and grilled mahi-mahi. It’s a postcard-perfect scene. But a century ago, this exact spot—the site of the Key West turtle kraals—smelled a whole lot different. It smelled like industry. Specifically, an industry built on the backs of green sea turtles.
Most people visiting the Florida Keys today see "Turtle Kraals" as a name on a restaurant sign or a waypoint near the ferry terminal. They don't realize they're standing on the site of what was once a global epicenter for turtle canning. It wasn't just a local snack. We’re talking about a massive operation that shipped turtle soup to fine dining rooms in London and New York.
What "Kraal" Actually Means
First off, let's clear up the word itself. "Kraal" isn't some fancy Floridian marketing term. It’s actually a Dutch/Afrikaans word for an enclosure or corral. Think of it like a liquid livestock pen.
Back in the 1800s and early 1900s, there was no refrigeration. You couldn't just freeze turtle meat and ship it. To keep the meat fresh, you had to keep the animal alive until the very last second. These "kraals" were essentially ocean-side pens made of sturdy wooden pilings driven into the seabed. Hunters would bring in massive sea turtles—sometimes weighing 500 pounds or more—and dump them into these pens. They’d wait there, swimming in circles in the shallow water, until the cannery was ready for them. It was efficient. It was also, by modern standards, pretty brutal.
The green sea turtle was the prize. Why? Because of the "calipee." This is the gelatinous fatty substance found in the lower shell. That’s the secret ingredient that gave turtle soup its famous texture. If you were a high-society diner in 1905, turtle soup was the ultimate status symbol. It was the "caviar" of the Victorian era.
The Rise and Fall of the Key West Turtle Kraals
Key West was the perfect hub for this. It had the deep-water port and proximity to the Caribbean nesting grounds. By the mid-1800s, the A. Granday Canning Company was the big player in town. They basically turned sea turtles into a global commodity.

By the 1890s, the industry was peaking. Thousands of turtles were processed every single year. You’d have schooners arriving from the Cayman Islands and the coast of Nicaragua, their decks piled high with live turtles flipped on their backs to keep them from crawling away. They’d be lowered into the Key West turtle kraals to await their fate. Honestly, it’s hard to imagine the scale of it now when we get excited just seeing one turtle surface for air while we’re snorkeling.
But the industry was its own worst enemy. You can't just keep taking thousands of slow-growing, late-maturing reptiles out of the ocean without consequences. By the 1930s, the populations were crashing. The turtles were getting smaller, and the hunters had to go further and further away to find them. Then came the Endangered Species Act of 1973. That was the final nail in the coffin. Commercial harvesting of green sea turtles became illegal, and the canning factory shut its doors for good.
Visiting the Site Today
Today, the physical location of the Key West turtle kraals is part of the Key West Bight. It’s been repurposed into a museum and restaurant area. If you go to the Turtle Museum (located right at the foot of Margaret St.), you can see the old cannery equipment.
It’s a small, open-air museum. Very "old Key West" vibes. You’ll see the massive iron kettles where they used to boil the meat. You’ll see the black-and-white photos of men standing next to turtles that look like small Volkswagens. It’s sobering. You realize that the very thing that built the economy of this island nearly wiped out a species.
- The Museum: It’s free. Run by the Mel Fisher Maritime Heritage Society. It’s worth the 20 minutes it takes to walk through.
- The Waterfront: You can still see the remnants of the pens. Look down into the water near the docks. You’ll see the structure that defines the historic bight.
- The Modern View: Ironically, the area is now a sanctuary. You’ll often see tarpon weighing 100 pounds hanging out by the docks, waiting for scraps from the charter boats.
Why We Should Care About the History
History isn't just about dates. It’s about how we shifted from seeing the ocean as an infinite larder to seeing it as a fragile ecosystem. The Key West turtle kraals represent that shift.

Back then, nobody thought turtles would run out. They were just "sea cattle." Today, Key West is one of the most proactive places for sea turtle conservation. If you find a sick or injured turtle in the Keys now, you call the Turtle Hospital in Marathon. They have converted an old motel into a state-of-the-art surgery center. It’s the total opposite of the old kraals.
One of the most interesting things about the old kraals is how they influenced the local diet. "Bollo" (a savory fritter) and turtle steaks were staples. When the ban hit, the culture had to pivot. That’s partly why conch (pronounced "konk") became the iconic food of the Keys. When you couldn't eat turtle anymore, the conch became the king of the menu. Though, ironically, local conch is now also protected, and most of what you eat in Key West today is actually imported from the Bahamas or Belize.
The Science of the "Green" Turtle
The green turtle (Chelonia mydas) got its name not from its shell color, but from the color of its fat. Because they mostly eat seagrass and algae as adults, their internal fat takes on a greenish tint. This was the specific fat that created the "green turtle soup" craze.
In the heyday of the Key West turtle kraals, researchers weren't really tracking migration patterns. We know now that these turtles travel thousands of miles. A turtle caught off the coast of Central America and brought to a kraal in Key West might have hatched on a beach in a completely different country. The industry was accidentally disrupting the ecology of the entire Caribbean basin.
How to Explore This History Personally

Start at the Sails to Rails Museum. It’s located in the same general area and gives a much broader context of how the Florida East Coast Railway changed everything. Before the railroad, the turtles had to be canned. Once the railroad arrived in 1912, they could ship live turtles and fresh meat north much faster.
Then, walk over to the Turtle Museum at the Bight. Look at the size of the shells on the wall. It gives you a sense of scale that a textbook can't. These were ancient, massive creatures.
Finally, if you have the time, take the drive up to Marathon (about an hour and fifteen minutes north) to the Turtle Hospital. Seeing a turtle getting an MRI or being treated for "bubble butt" syndrome (where air gets trapped under their shell, preventing them from diving) is the perfect emotional counterpoint to the history of the kraals.
Actionable Tips for the Modern Traveler
- Check the Tide: When visiting the historic bight, go during a moving tide. The water is clearer, and you’re more likely to see the large marine life (tarpon, manatees, and occasionally a wild turtle) that hangs around the old kraal pilings.
- Look for the Plaques: There are several historical markers along the Harbor Walk. They aren't flashy, but they explain exactly where the canning lines used to sit.
- Support Local Conservation: Instead of buying "turtle shell" souvenirs (which are almost always illegal or fake anyway), look for local shops that donate to the Sea Turtle Conservancy.
- Visit the Cemetery: Sounds weird, right? But the Key West Cemetery has the graves of many of the "Turtle Kings"—the wealthy merchants who ran the kraals. Their headstones are a testament to how much money this industry once generated.
The Key West turtle kraals are a reminder that the "Good Old Days" were often complicated. We lost a massive part of our natural heritage, but we gained a deep-seated respect for the animals that remain. Walking those docks today, you aren't just looking at a tourist trap. You're looking at a site of profound ecological transformation.
Next time you're standing on the docks at sunset, look past the charter boats and the sunset cruises. Imagine the schooners. Imagine the splash of a 400-pound green turtle being lowered into the water. It makes the island feel a whole lot older, and a whole lot more significant.
Key Takeaways for Your Visit:
- Location: 200 Margaret Street, Key West, FL.
- Cost: The outdoor displays and waterfront views are free.
- Context: This was the last functional turtle cannery in the United States.
- Impact: The closure of the kraals marked the beginning of modern marine conservation in the Florida Keys.
The transition from exploitation to education is complete. The kraals no longer hold captives; they hold stories. Every piling and every rusted kettle in the museum tells the tale of an island that learned to value its wildlife more alive than in a soup tin. It's a rare example of a place that looked at its primary industry, realized it was destructive, and found a way to move forward without erasing its past.
