The Story
Built in 1932 at Dinner Key, this seaplane hangar anchored the first permanent Coast Guard Air Station in the country. From here, seaplanes lumbered off Biscayne Bay to carry out rescues and evacuations across Florida's coasts and the Straits beyond. It stands from the pioneering days when aviation was still being folded into the nation's maritime lifesaving service.
Why it matters
As home to the country's first permanent Coast Guard Air Station, the site marks the birth of a national air-rescue tradition that has since saved countless lives at sea.
The story behind this marker
AI contextThe era
By the early 1930s, aviation was young, but the idea of using aircraft to save lives at sea was just coming of age. The United States Coast Guard, whose mission has always been rescue and protection along the nation's waters, was beginning to add wings to that work — and Florida, with its long coastlines and busy sea lanes, was a natural place to do it.
This seaplane hangar, built in 1932 at Dinner Key on Biscayne Bay in Miami, anchored the first permanent Coast Guard Air Station in the country. Dinner Key was well suited to it: a sheltered stretch of bay where flying boats could taxi off the water and lumber into the air. In an era when aircraft were still fragile and airfields scarce, seaplanes that used the water itself as a runway made perfect sense along the coast.
Miami in these years was a city looking toward the sea and the sky at once — a gateway to the Caribbean and a growing hub of early aviation. A permanent Coast Guard air station here placed rescue aircraft exactly where the nation's maritime traffic and its subtropical dangers came together.
People & events
The crews who flew from Dinner Key were pioneers of a mission we now take for granted: the airborne rescue. From this hangar, seaplanes headed out over Florida's coasts and the waters beyond to carry out rescues and evacuations, reaching people in trouble faster than any boat could.
That work took a particular kind of nerve. Early seaplanes were demanding machines, and setting one down on open water to pull someone to safety was dangerous, skilled flying. The men who did it were writing the playbook as they went, proving that aircraft belonged in the lifesaving service and not just the military.
The hangar was the heart of all of it — the place where the planes were kept, readied, and sent out, and where they returned. Every rescue and evacuation launched from Dinner Key passed through this building first. It stands as the physical center of those pioneering days, when the Coast Guard was still learning what aviation could do for the people it was sworn to protect.
Its place in the American story
As home to the first permanent Coast Guard Air Station in the country, this site marks a genuine beginning. The tradition of Coast Guard air rescue — the helicopters and aircraft that today pluck mariners from storms and floods across the nation — has roots that run back to stations like this one, where the idea was first made permanent.
That lineage matters. Folding aviation into the maritime lifesaving service transformed what rescue at sea could mean: a plane could search a stretch of water in minutes that a boat would take hours to cover, and reach the stranded before it was too late. Beginning that work in a lasting, dedicated way was a real turning point.
The hangar, then, is more than an old aviation building. It represents the birth of a national air-rescue tradition that has since saved countless lives — the moment the Coast Guard's oldest duty, saving people from the sea, took to the air for good.
If you visit
Look first at the building itself. A seaplane hangar from 1932 was designed around the water — built so flying boats could move between the bay and shelter — and reading its shape and scale tells you how early aviators worked with the sea rather than against it.
Let the setting on Biscayne Bay do its part. Picture the water not as scenery but as a runway: aircraft taxiing out, lifting off the surface, and heading for someone in trouble beyond the horizon. That image is what turns an old hangar into a living piece of history.
It's a rewarding stop for anyone interested in flight, the sea, or the long story of rescue, and it fits naturally into a day exploring Miami's waterfront and its early aviation heritage. Stand where the planes once launched, and you're standing at the start of a tradition that still saves lives today.

Indian Haulover
Fort Lauderdale, FL
Long before a marina occupied this ground, Native people carried their canoes across the narrow neck of land here — a "haulover" linking New River Sound to the open Atlantic. In 1838, during the Second Seminole War, the army built a fort near this spot and named it for Major William Lauderdale, a name the growing city would later inherit. The post stayed active until the war's end in 1842.
Former Site of Fleischer Studios
Miami, FL
From 1938 to 1943, the pioneering animation house Fleischer Studios operated from Miami, having relocated south from New York. Founded by brothers Max and Dave Fleischer, the studio was Walt Disney's chief early rival, known for Betty Boop, Popeye, and a landmark series of Superman cartoons whose lush, rotoscoped style influenced animation for decades. Their Miami years produced ambitious feature work before the studio was absorbed by its parent company and the operation wound down.
Biscayne House of Refuge
Miami Beach, FL
Near this spot once stood the Biscayne House of Refuge, part of the chain of lifesaving stations that guarded Florida's lonely Atlantic beaches in the late nineteenth century. After every storm, its keeper and his family would walk the shore searching for castaways, offering food, dry clothing, and shelter to those the sea had spared. On a coast then largely empty of settlement, such a station was often the only hope of survival for a shipwrecked sailor.
Larry and Penny Park's WWII Air Station Arrow
Miami-Dade County, FL
During World War II the U.S. Navy blanketed South Florida with air stations to train pilots for the war in the Atlantic and Pacific, and this parkland began life as part of one of them in 1942. A 1945 hurricane wrecked the base, but a huge concrete directional arrow — pointing north to guide aircraft — still survives on the ground. Such arrows were part of early aviation's navigation network, later repurposed and remembered as relics of the flying age.
