Naval Security Group station (1935-2002)
The Story
On the coast of Down East Maine, this site housed a U.S. Navy communications and signals-intelligence station that operated from 1935 until 2002. Through World War II and the long decades of the Cold War, its antennas along the Atlantic quietly gathered and relayed the kind of intelligence that rarely made headlines but shaped national security.

The story behind this marker
AI contextThe era
On the coast of Down East Maine, in the town of Gouldsboro at the far eastern edge of the United States, this site housed a U.S. Navy communications and signals-intelligence station that operated from 1935 until 2002. Its span alone tells a remarkable story: it was born before the Second World War and lived on until the twenty-first century.
The geography is the point. This is a remote, rugged stretch of the Atlantic seaboard, and that remoteness was an asset. A quiet coastal location, far from cities and interference, was ideal for the kind of work the station did — listening across the ocean, gathering signals, and relaying communications for the Navy.
The station's life spanned two great eras of twentieth-century conflict. It served through World War II, when the Atlantic itself was a battleground, and then through the long decades of the Cold War, when the contest between the United States and the Soviet Union made electronic intelligence more important than ever. For nearly seventy years, its antennas quietly did their work along the Maine coast.
People & events
The inscription is brief — it simply names the station and its span of years, 1935 to 2002 — but those dates frame a whole hidden history. During the Second World War, a station like this was part of the vast effort to monitor the airwaves and support naval operations across the embattled Atlantic, work that was secret then and rarely celebrated even now.
Through the Cold War that followed, the mission continued and deepened. Signals-intelligence and communications stations became essential to the era's quiet, constant vigilance, keeping watch on a rival superpower without a shot being fired. The people who served here worked in a world of antennas, receivers, and classified traffic rather than of visible battle.
Because the work was secret by nature, the individual stories are largely untold. But generations of naval personnel passed through this remote post over its nearly seven decades, doing the unglamorous, exacting work of listening. In 2002, after a long and quiet service, the station's chapter closed.
Its place in the American story
Remote listening stations like this one reveal the hidden infrastructure of twentieth-century American defense. The dramatic history of the era — the great battles of World War II, the tense standoffs of the Cold War — rested on a foundation of quiet, technical work carried out at places most citizens never knew existed.
Signals intelligence and secure communications were among the most important, and most secret, tools a nation had. A station on the Maine coast, invisible in the headlines, was part of the same effort that helped win a world war and then hold a decades-long peace. Its very obscurity was a measure of how well it did its job.
That this single site served continuously from 1935 to 2002 makes it a rare thread connecting the whole arc of America's mid-century defense, from the run-up to World War II through the end of the Cold War. It stands for a whole network of such places whose contributions were, by design, kept out of view.
If you visit
This is Down East Maine, so the journey itself is part of the reward — a drive out along a rugged, beautiful stretch of the Atlantic coast, far from the crowds. Come for that setting and let the history deepen it.
At the site, let your imagination do the work the secrecy once prevented. There are no dramatic battlefields to see here; the story is about listening, about antennas along the shore quietly gathering intelligence for nearly seventy years. Stand and consider how much consequential history can happen in a place that looks, at a glance, like empty coastline.
It's a rewarding stop for travelers drawn to the quieter, hidden corners of American history rather than the obvious monuments. Pair it with the wider pleasures of the Hancock County coast, and let the marker remind you that even this remote shore had a role in the nation's defense.

Princeton War Monument
Princeton, ME
The town of Princeton in eastern Maine raised this monument to honor all of its war veterans, without singling out any one conflict. It stands as a small community's collective salute to the neighbors who left the woods and waterways of Washington County to serve.
Arthur Noble Memorial
Nobleboro, ME
This monument honors Arthur Noble, a Lieutenant Colonel of the Second Massachusetts Regiment who took part in the 1745 siege and capture of the French fortress of Louisbourg on Cape Breton Island. The expedition, mounted largely by New England colonial militia, was one of the most striking colonial military feats of the era, seizing a stronghold thought nearly impregnable. Noble, a settler of the Maine coast, was among the New Englanders drawn into the imperial wars between Britain and France.
All Wars Monument
South Bristol, ME
This granite memorial in the small fishing town of South Bristol honors Wellington MacFarland Jordan, a young infantryman who was born in 1891 and died in service at Camp Devens, Massachusetts, in his early twenties. A local road was renamed in his memory, and the town later broadened the monument to salute all its veterans across every American conflict. It reflects the way small New England communities wove a single lost son's name into a lasting tribute to collective service.
Blue Star Memorial
Boothbay Harbor, ME
This Blue Star Memorial pays tribute to the men and women of the U.S. Armed Forces. The Blue Star program began in 1945, when garden clubs planted memorial highways honoring the service members of World War II; it takes its name from the blue-star service flags families hung in their windows for loved ones in uniform. The tributes later broadened to salute those who have served in all of America's wars.
