Ever wondered about that massive concrete pier jutting into Key West Harbor? You know—the one where those giant cruise ships dock like they own the place? That’s the Outer Mole, and this thing has stories.
What started as a rickety wooden dock for a Civil War fort has evolved into one of the most strategically important (and restricted) piers in Florida. From Confederate blockade runners to modern mega-ships carrying thousands of passengers, the Outer Mole has been the backbone of Key West’s harbor for over 180 years.
Ready to dive into some seriously cool maritime history? Let’s explore how this humble wooden dock became the concrete giant that welcomes cruise ships today.
From Fortress to Harbor: The Wooden Dock Era (1845-1900s)
Picture this: It’s 1845, and Fort Zachary Taylor isn’t the beachside attraction you know today. Nope—this fortress sat about 1,000 feet offshore, connected to Key West by a wooden causeway and drawbridge. Talk about maximum security.
The fort sat on what military folks called a “cover-face” (basically a small piece of fortified land), and extending from that cover-face was a wooden dock. This humble pier was the original Outer Mole—the lifeline that brought supplies, ammunition, and probably the occasional bottle of rum to the isolated garrison.
Why Key West Mattered
Key West wasn’t just some random tropical outpost. This island sat at the crossroads of major shipping lanes, making it crucial for controlling access to the Gulf of Mexico. During the Civil War, Union forces used Fort Taylor to enforce their naval blockade of Confederate ports. Those wooden docks? They were busy loading and unloading everything needed to keep that strategic operation running.
Imagine the scene: wooden ships creaking in the harbor, coal smoke drifting across the water, sailors shouting orders, and that rickety pier serving as the connection between military might and island life.

Engineering Meets Ambition: The Concrete Revolution (1918-1920s)
Fast-forward to after World War I, when the Navy had bigger plans for Key West. Those charming wooden docks? Not gonna cut it for the modern military machine they had in mind.
The solution was revolutionary for its time: a massive concrete breakwater that would serve double duty as both a protective barrier and a deep-water pier. Engineers filled the concrete structure with sand and marl dredged from the seabed, creating something that could handle the biggest ships of the era.
The Numbers That Matter
- Length: 580 feet of solid concrete
- Deck height: 7 feet above water
- Capacity: Ships up to 855 feet long (some sources say up to 1,040 feet under special arrangements)
- Construction: Concrete filled with sand and marl from the ocean floor
This wasn’t just about making a bigger dock—it was about transforming Key West into a legitimate submarine base. The new Outer Mole could protect vessels from rough seas while providing the deep-water access needed for military operations.

War, Submarines, and Strategic Importance (1920s-1986)
The concrete Outer Mole quickly became the heart of Key West’s naval operations. During its military heyday, this pier hosted everything from submarines to destroyers, playing a crucial role in coastal defense and anti-submarine training.
The Cold War Connection
Key West’s location—just 90 miles from Cuba—made it incredibly valuable during World War II and the Cold War. The Outer Mole provided a secure berthing spot for vessels conducting surveillance, training missions, and coastal patrols in some of the most strategically important waters in the Western Hemisphere.
Fun fact: Even after the Navy sold most of the old naval station property at public auction in 1986, they held onto the Outer Mole. Why? Because some things are too important to let go.
Modern Times: Navy Meets Tourism (1986-Present)
Here’s where things get interesting. The Navy still owns the Outer Mole, but they lease access to the City of Key West for cruise ship operations. It’s like the ultimate roommate situation—military vessels and cruise passengers sharing the same space.
Who Uses the Outer Mole Today?
- U.S. Navy: Still the official owner and primary user
- U.S. Coast Guard: Regular operations and vessel maintenance
- NOAA: Research vessels and oceanographic missions
- Cruise Lines: Large ships that need deep-water access
What This Means for Cruise Passengers
If your ship docks at the Outer Mole, don’t expect to just walk off and stroll into town. Since it’s still Navy property, cruise passengers must take shuttles through the base area to reach public areas. It’s a small reminder that you’re visiting an active military facility that happens to welcome tourists.
Why the Outer Mole Still Matters
The Outer Mole represents something pretty remarkable: infrastructure built for war that now serves peace. It’s a concrete symbol of how Key West has evolved from military outpost to tourist destination while maintaining its strategic importance.
For History Buffs
Walking to the end of Southard Street and looking out at the Outer Mole, you’re seeing 180 years of continuous use in one spot. That’s American ingenuity and adaptation at work.
For Visitors
Whether you arrive on a cruise ship or just want to watch the maritime traffic, the Outer Mole offers a unique glimpse into Key West’s dual identity as both military installation and tropical paradise.
Planning Your Visit
Historic Marker #44 sits at the end of Southard Street, right where you can get the best view of the Outer Mole. It’s worth the walk, especially at sunset when you can watch cruise ships, Coast Guard cutters, or Navy vessels silhouetted against the Key West sky.
Pro tip: Check the City of Key West’s cruise ship calendar to see what’s docking when. You might catch everything from a massive cruise liner to a sleek Navy vessel sharing the same pier.
The Bigger Picture
The Outer Mole proves that the best infrastructure adapts rather than becomes obsolete. What began as a wooden dock supporting a Civil War fortress evolved into a concrete breakwater protecting submarines, and now serves as a gateway for tourists exploring Key West’s unique blend of military history and island culture.
Next time you see a cruise ship gliding into Key West Harbor, remember: that concrete pier welcoming thousands of vacation-bound passengers once harbored World War II submarines and Cold War vessels. It’s the perfect metaphor for Key West itself—where serious history and serious fun have always gone hand in hand.
