The Story
Just to the north lies Passage Key, a low sand island that marks the southern entrance to Tampa Bay. Ever since Ponce de León probed this coast in 1513, mariners have used the key to steer safely into the great bay the early Spanish called the Bahía del Espíritu Santo. For centuries it has served as a natural navigational landmark on Florida's Gulf shore.
Why it matters
The key connects modern Tampa Bay to the very dawn of European exploration in North America, when Spanish ships first charted Florida's Gulf coast.
The story behind this marker
AI contextThe era
The marker points north to Passage Key, a low sand island at the mouth of Tampa Bay — and in doing so it reaches back to the very first chapter of European contact with what is now the United States. This is Florida's Gulf coast, a shoreline of shifting sand islands, shallow passes, and one magnificent natural harbor: the great bay beyond.
In 1513, when Ponce de León explored this coast, Europe barely knew Florida existed. He and the Spanish who followed were feeling their way along an unknown shore, charting entrances and dangers, giving names to a land whose peoples had lived here for thousands of years. To early Spanish explorers, the bay beyond this pass was grand enough to be called the Bahía del Espíritu Santo — the Bay of the Holy Spirit.
What made a small sand key matter, then and for centuries after, was geography. A ship approaching a great bay needs to know where the safe entrance lies. A low island sitting at the southern mouth of the bay becomes a fixed point on the water — a natural signpost telling a mariner where to turn in.
People & events
The figure named here is Juan Ponce de León, whose 1513 voyage along this coast is the event the marker commemorates. He is remembered as one of the first Europeans to reach and explore Florida, and his name is forever tied to the Spanish opening of the peninsula. The marker is careful and correct in keeping to that well-established ground: it credits him with exploring this coast, and lets the geography carry the rest of the story.
And the geography is the real protagonist. Ever since those first Spanish sails appeared, Passage Key has done the same quiet job — marking the southerly entrance into Tampa Bay and guiding ships into the great bay beyond. Generations of mariners, Spanish and everyone after, read this low island the way a traveler reads a familiar landmark on a long road.
The name the early Spanish gave the bay, the Bahía del Espíritu Santo, is a small artifact of that first encounter — a reminder that explorers didn't just chart this coast, they draped it in the language and faith they carried across the ocean. The pass endures even as the names have changed around it.
Its place in the American story
It is easy to forget how early the European story begins on Florida's Gulf shore. The 1513 voyage that this marker recalls came decades before the more famous English settlements far to the north — a reminder that the first European chapters of the American story were written in Spanish, and written here in the south long before anywhere else.
Tampa Bay would grow into one of the Gulf's great harbors, and the humble key at its mouth is the through-line connecting that modern port to the age of first exploration. The same island that steers ships today was steering them when the coast was brand new to European eyes.
That continuity is the point. Few places let you draw a straight line from the dawn of European exploration in North America to a working bay of the present day. Passage Key is such a place — a small, unglamorous island that has quietly done one important job across five centuries.
If you visit
From this spot on Anna Maria Island, look north across the water toward the low sand key that guards the entrance to Tampa Bay. It is not a dramatic landmark — that is exactly what makes its long usefulness so remarkable. A sailor's most valuable marks are often the plainest ones.
Let the view do the historical work. You are looking at the same southern gateway that Spanish ships sought out five centuries ago, and that vessels still use to find their way into the great bay beyond. Imagine those first explorers reading this coast with no chart to help them.
Anna Maria Island's Gulf beaches make an easy and beautiful base for this kind of history. Pair the overlook with a walk along the shore, and you'll have the whole scene: open Gulf on one side, the sheltered bay on the other, and between them a small island that has pointed the way for longer than the nation itself has existed.

Colonel Joe Kittinger Park
Orlando, FL
This Orlando park honors Joe Kittinger, an Air Force test pilot celebrated as a pioneer of the edge of space. In the Project Excelsior high-altitude balloon program around 1960, he rode an open gondola to the stratosphere and made record-shattering parachute jumps, gathering data that helped make crewed spaceflight survivable. Decades later, in 1984, he became the first person to cross the Atlantic solo in a gas balloon.
Tin City
Naples, FL
Tin City traces its roots to 1920s Naples, when property leased near the Gordon River drew pioneering commercial fishing families to the waterfront. They raised docks and tin-roofed sheds to clam, fish, and process their catch, giving the humble district both its livelihood and its name. Those weathered buildings later found new life as one of Naples' distinctive shopping and dining destinations.
Naples Municipal Airport
Naples, FL
Before jetliners and snowbird traffic, this stretch of Southwest Florida was cattle country: the airfield rose on land that had been the Henry Youngman dairy farm. During World War II the U.S. military transformed it into a training base, part of the vast network of Florida airfields that took advantage of the state's flat terrain and clear skies to prepare aircrews for the war. In the peacetime decades that followed, the field found new life as a commercial gateway, with Naples Airlines—later Provincetown-Boston Airline (PBA)—flying connecting routes out of Naples under owner Mr. Van Arsdale, Sr.
Back Bay — Naples' First Mooring
Naples, FL
Settled in 1915, this "Back Bay" district gave the young town of Naples its first sheltered mooring, making it the natural gathering place for the community's pioneers. From here workers helped push through the Tamiami Trail linking Tampa and Miami across the Everglades, while the local fishing industry, the first pharmacy, and the first newspaper all took root nearby. It was, in effect, the working heart of frontier Naples in the decades before the city became a resort destination.
