The Story
On the wind-scoured dunes of Cape Cod, Guglielmo Marconi's company raised a ring of towering wooden masts and, in January 1903, sent the first transatlantic wireless message originating on American soil — a greeting exchanged between President Theodore Roosevelt and King Edward VII of Great Britain. The station, built in 1901–1902 by the Marconi Wireless Telegraph Company of America, proved that words could leap the ocean with no cable beneath them. The Atlantic surf has since claimed the original towers, but the bluff where they stood remains a birthplace of modern communication.
Why it matters
This lonely Wellfleet bluff marks the moment wireless telegraphy bridged continents from American shores, launching the age of radio and the company that would become RCA.
The story behind this marker
AI contextThe era
At the dawn of the twentieth century, the fastest way to send a message across the Atlantic was through a copper cable lying on the ocean floor. It worked, but it was expensive, tightly controlled, and bound to physical wire. The idea that words could simply leap the ocean through the open air, with nothing between the shores but empty sky, struck many people as close to magic.
Cape Cod in those years was a windswept, thinly settled stretch of dunes and bluffs facing the North Atlantic — an unlikely birthplace for a technological revolution, but a perfect one. Its high, open ground looked straight out to sea toward Europe, exactly what an experimental wireless station needed.
Into that landscape, in 1901 and 1902, came a ring of towering wooden masts raised on the bluff at Wellfleet. It was one of the boldest engineering gambles of the age: an attempt to prove that a signal could be flung clear across the ocean without a single strand of wire beneath it.
People & events
The station was built by the Marconi Wireless Telegraph Company of America, the firm founded on the work of the pioneering inventor Guglielmo Marconi. On January 19, 1903, from this Cape Cod bluff, the station transmitted the first transatlantic wireless telegram to originate on United States soil.
The message was no ordinary test signal. It carried a greeting exchanged between President Theodore Roosevelt and King Edward VII of Great Britain — heads of two great nations speaking to one another, for the first time from American shores, through the air itself. The choice of correspondents made the point unmistakable: this was a moment of state, not just a laboratory success.
The fierce Atlantic weather that made the site useful also proved its undoing. Over the following decades, erosion gnawed at the bluff, and the original towers were eventually lost to the sea. What survives is the ground itself and the memory of what was accomplished there.
Its place in the American story
This lonely bluff marks the moment wireless telegraphy bridged continents from the American coast. From that first message flowed a technology that would remake the world — ship-to-shore communication that saved lives at sea, then broadcast radio, and ultimately the whole age of instantaneous long-distance communication we now take for granted.
There is a direct corporate thread here, too. The marker notes that the Marconi Wireless Telegraph Company of America was the predecessor of RCA — the Radio Corporation of America — one of the giants that would define broadcasting in the twentieth century. The line from this dune to the golden age of radio runs unbroken.
It is fitting that the first such message linked an American president and a British king. Wireless would go on to shrink the distance between nations, and it began, on the American side, with two leaders greeting each other across an ocean that had always kept them apart.
If you visit
Come for the setting as much as the history. The bluff at Wellfleet is exposed to the full force of the Atlantic wind, and standing there you feel immediately why Marconi's engineers chose it — the ground is high, the sea view is enormous, and Europe lies somewhere out past the horizon.
Don't expect the great masts; the ocean has taken the original towers, and much of the ground they stood on. That absence is part of the experience. Look out at the surf eating away at the bluff and you understand both the ambition of the station and the relentless power that eventually reclaimed it.
This is a place for imagination. Stand where the towers once rose, picture the crackle of the first signal racing out over the water, and consider that the modern connected world can trace part of its lineage to this quiet, eroding edge of Cape Cod. It pairs naturally with a day of walking the dunes and shoreline of the Outer Cape.

Guglielmo Marconi, Edward VII, and Theodore Roosevelt
Wellfleet, MA · est. 1953
On the Wellfleet bluffs Guglielmo Marconi's company built the first U.S. transatlantic wireless station in 1901–1902, part of the race to send messages across the ocean without cables. In January 1903 the station carried the first U.S. transatlantic wireless telegram, an exchange of greetings between President Theodore Roosevelt and King Edward VII. Marconi's American venture would later become a predecessor of RCA.
Albert Champion
Boston, MA
The Cyclorama Building was raised in 1884 to house a giant circular painting of the Battle of Gettysburg — a form of immersive entertainment popular before motion pictures (that canvas now hangs at Gettysburg National Military Park). Over the years the round hall served as a skating rink, garage, and flower market, and in 1907 it was here that Albert Champion developed his spark plug, a small invention vital to the automobile age. Since 1970 the building has been home to the Boston Center for the Arts.
Edwin Herbert Land Memorial
Cambridge, MA
This Cambridge tribute honors Dr. Edwin Herbert Land (1909–1991), the inventor and entrepreneur whose experiments with light and polarization led to the Polaroid Corporation and the instant camera that made a photograph appear in seconds. A largely self-taught scientist, he held hundreds of patents and advised the nation on science and defense, earning the Presidential Medal of Freedom. His maxims — undertake only what is 'manifestly important or nearly impossible' — capture a restless, world-changing curiosity.
Stephen Daye
Cambridge, MA
In 1638, on ground near this spot, Stephen Daye operated the first printing press in Britain's American colonies. From it came almanacs, legal forms, and the famous Bay Psalm Book — the earliest books printed in English North America.
