Site of the first United States transatlantic wireless telegraph station built in 1901-1902. Marconi Wireless Telegraph Company of America predecessor of RCA transmitted January 19, 1903 the first U.S. transatlantic wireless telegram addressed to Edward VII King of England by Theodore Roosevelt President of the United States of America

The Story
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.
Why it matters
The station marks the dawn of instantaneous transatlantic communication, a leap that shrank the distance between nations and helped launch the modern age of wireless.
The story behind this marker
AI contextThe era
At the turn of the twentieth century, the world still moved at the speed of a ship. A message from Washington to London traveled either by undersea cable — a marvel of the age, but owned by a handful of companies and prone to breaks in the deep — or in the hold of a steamer, days out to sea. The idea that words might simply leap the ocean through the empty air struck most people as very close to magic.
The outer arm of Cape Cod was, for that experiment, close to ideal. The bluffs at Wellfleet stood high and open, facing nothing but water all the way to Europe, with room for the tall wooden towers and the web of antenna wires the work demanded. It was a lonely, wind-scoured place, which was rather the point.
This was the Progressive era, a time enchanted by invention and by the promise that new machines would knit distant peoples closer together. Wireless telegraphy sat at the very front of that hope, and the little station built here in 1901 and 1902 was America's stake in a race being run on both shores of the Atlantic.
People & events
The station carried the name of Guglielmo Marconi, the young Italian inventor who had turned experiments with radio waves into a working business. His American company built and ran the Wellfleet station, one node in a growing network he was stringing across the ocean.
The moment that fixed this spot in history came in January 1903. From these bluffs, the station sent what the marker records as the first United States transatlantic wireless telegram — a message of greeting from Theodore Roosevelt, President of the United States, addressed across the sea to Edward VII, King of England.
Think about what that exchange represented. Two heads of state, an ocean apart, trading courtesies not through weeks of correspondence or the tap of a buried cable, but through signals flung invisibly through the sky. It was as much a ceremony as a technical feat — a way of announcing to the world that a new kind of communication had arrived and that nations meant to use it.
Its place in the American story
Marconi's American venture would not stay small. The marker notes that his company was a predecessor of RCA — the Radio Corporation of America — a name that would come to dominate broadcasting in the decades ahead. The wireless spark tested on this windy shore belonged to the same lineage as the radios that later filled American living rooms.
The larger story is one of distance collapsing. For all of human history, communication had crawled at the pace of the fastest ship or horse; the telegraph cable had quickened it, and now wireless promised to free it from wires altogether. Every later leap — ship-to-shore distress calls, transoceanic broadcasts, the global web of signals we now take for granted — traces back to early stations like this one.
That a routine exchange of pleasantries between a president and a king could be the headline says everything. The message hardly mattered; the medium was the news. Wellfleet marks the American dawn of the wireless age.
If you visit
Come for the setting as much as the history. This is the outer Cape, where the land narrows to a fragile arm and the Atlantic stretches unbroken to the horizon. Stand on the bluff, let the wind push at you, and imagine tall wooden towers rising here more than a century ago, strung with wires meant to catch the empty air.
The sea has been steadily eating away at these cliffs, so the ground itself is part of the story — a reminder that even a landmark of the modern age sits on shifting sand. Look out toward the water and picture the direction those first signals traveled, out past the last of the land and on toward England.
It fits naturally into a day exploring the outer Cape's beaches and dunes. Pair it with a walk along the shore and you'll feel why engineers chose this exposed, wide-open perch — the same emptiness that makes the view so bracing today is exactly what made it perfect for reaching across an ocean.

Marconi Station Site
Wellfleet, MA
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.
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.
