12 FEB 2026 · Beneath our feet, entire worlds exist in silence. From the Raven Rock Mountain Complex in Pennsylvania to the vast, hollowed-out caverns of Mount Weather, governments have spent decades building massive underground fortresses. Officially, they are for "continuity of government" in the event of nuclear war. But the sheer scale, secrecy, and specific locations of these bunkers have fueled decades of speculation.
In this episode of Unexplained History, host Tom McKenzie descends into the classified world of subterranean bases. We investigate the confirmed existence of deep underground military bases (DUMBs), the chilling "Project Greek Island" that hid a bunker under a luxury resort for 30 years, and the persistent rumors of high-speed underground transit systems connecting them. Are these just Cold War relics, or are they preparing for a future catastrophe we haven't been told about?

10 FEB 2026 · In Brittany, France, thousands of massive standing stones stretch across the landscape like a frozen army. They form the Carnac Alignments—the largest megalithic site in the world, predating Stonehenge and the Pyramids. Who built them? Why were they arranged in such precise, geometric lines? And why did they stop?
In this episode of Unexplained History, host Tom McKenzie investigates the enigma of Carnac. We explore the ancient engineering required to move these multi-ton giants, the folklore that claims they are petrified Roman soldiers, and the modern scientific theories suggesting they were a sophisticated Neolithic observatory or a seismic detector. From the local legends of "Saint Cornely" to the controversial restorations that may have altered the site forever, we uncover the secrets of a landscape that refuses to be explained.

5 FEB 2026 · On October 13, 1917, in a muddy field in Fátima, Portugal, tens of thousands of people gathered in the rain, waiting for a promised miracle from three shepherd children. What happened next defied explanation. According to witnesses, the sun danced in the sky, spun like a wheel of fire, and plunged toward the earth, drying the soaked crowd in an instant.
Was it a genuine divine intervention, a rare atmospheric phenomenon, or a collective psychological event triggered by war, hunger, and desperation?
In this episode of Unexplained History, host Tom McKenzie investigates the Miracle of the Sun. We explore the prophecies of the three children—Lucia, Francisco, and Jacinta—the secrets they guarded for decades, and the scientific theories attempting to rationalize the impossible.
From the "Third Secret" locked away in the Vatican to the chilling details of that October day, we unravel the mystery that still divides believers and skeptics a century later. Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.

3 FEB 2026 · Around 1200 BCE, the civilized world came to a sudden, violent end. The Hittite Empire burned, Mycenaean palaces crumbled, and Egypt fought for its life. The culprits? A mysterious, seafaring confederation known to history only as the Sea Peoples.
In this episode of Unexplained History, host Tom McKenzie investigates the greatest cold case of antiquity. We analyze the archaeological evidence from the ashes of Ugarit to the temple walls of Medinet Habu to answer the ultimate question: Who were these invaders?
We dive deep into:
- The Catastrophe: How the Bronze Age "Golden Era" vanished in a single lifetime.
- The Suspects: Were they the Philistines? Displaced Trojans? Mycenaean refugees?
- The Theories: Did drought, earthquakes, or systems collapse trigger the invasion?
- The Aftermath: How the ensuing "Dark Age" paved the way for Classical Greece.

29 JAN 2026 · Dive into the shadows of the Cold War with host Tom McKenzie as Unexplained History uncovers the chilling reality of Project MKUltra. In this episode, we peel back the layers of the CIA’s most infamous and illegal operation: a top-secret quest for mind control.
From the tragic death of scientist Frank Olson to the halls of the Allan Memorial Institute in Montreal, we investigate the dark experiments led by Sidney Gottlieb. Discover how LSD, hypnosis, and sensory deprivation were weaponized against unwitting citizens in a desperate bid to outpace the Soviets.
We also examine the massive cover-up ordered by CIA Director Richard Helms in 1973 and the lingering questions that remain today.

27 JAN 2026 · Join host Tom McKenzie on Unexplained History as we unroll one of the world's most baffling cartographic mysteries: the Piri Reis Map. Discovered in the dusty archives of Istanbul’s Topkapi Palace in 1929, this gazelle-skin chart drawn by an Ottoman Admiral in 1513 contains details that shouldn't exist.
How did Piri Reis depict the coastline of South America with such accuracy just decades after Columbus? And more chillingly, does the map truly show the coast of Antarctica free of ice, centuries before the continent was officially discovered? We examine the controversial theories of Charles Hapgood, the possibility of lost ancient civilizations, and the skeptical arguments regarding historical compilation.
Is this map a misunderstanding of geography, or evidence of a forgotten chapter in human history? Listen in to navigate the unknown. Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.

22 JAN 2026 · In the sands outside Baghdad, archaeologists uncovered a strange object that may challenge everything we think we know about ancient technology.
Known as the Baghdad Battery, this collection of clay jars, copper cylinders, and iron rods dates back nearly 2,000 years—and may have been capable of producing electricity long before the modern age.
In this episode of Unexplained History, we trace the discovery of the Baghdad Battery, the scientists who tested its electrical potential, and the fierce debate over its true purpose. Could ancient civilizations have used electricity for electroplating, medicine, or ritual practices? Or is this one of history’s most misunderstood artifacts?
We explore the Parthian Empire, experimental reconstructions, skeptical explanations, and fringe theories that suggest lost knowledge may have existed—and vanished—long before modern science.
Was the Baghdad Battery a revolutionary ancient invention… or a coincidence shaped by modern imagination? Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.

20 JAN 2026 · Television and radio were once trusted voices of authority—until something began breaking through the signal.
In this episode of Unexplained History, we investigate some of the most chilling and unexplained broadcast intrusions ever recorded. From the 1977 Southern Television hijacking where a voice claiming to represent the Ashtar Galactic Command interrupted the news, to the infamous Max Headroom broadcast hijacking that stunned Chicago in 1987, these events shattered public trust in the airwaves.
We explore how pirate signals, satellite hijackings, and mysterious intruders overpowered major broadcasters, baffled engineers, and evaded authorities. Who were the people behind these intrusions? Were they pranksters, protesters, psychological provocateurs—or something stranger?
By examining Cold War paranoia, early satellite technology, official investigations, and unresolved cases, we ask a disturbing question:
If someone can hijack the signal… who really controls reality? Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.

15 JAN 2026 · Long before farming, pottery, or metal tools, an ancient civilization may have built the world’s first known temple.
Göbekli Tepe, a 12,000-year-old megalithic site in southeastern Turkey, has forced archaeologists to rethink the very origins of human civilization. Massive T-shaped stone pillars, intricately carved with animals and symbols, were erected by hunter-gatherers thousands of years earlier than mainstream history believed possible.
In this episode of Unexplained History, we explore the mystery of Göbekli Tepe—its construction, its purpose, and why it was deliberately buried. We examine the Vulture Stone and its possible link to a cosmic catastrophe, the role of archaeoastronomy, and the researchers and alternative historians who argue this site represents lost knowledge from a forgotten age.
Was Göbekli Tepe the birthplace of organized religion? A forgotten center of ancient wisdom? Or evidence of a civilization erased from history?
Join us as we uncover why this ancient site continues to challenge everything we thought we knew about humanity’s past. Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.

13 JAN 2026 · In 1977, a British television broadcast shocked viewers with a chilling idea: Earth was facing environmental collapse, and a secret elite had already chosen an escape plan known as Alternative 3.
Framed as a serious scientific documentary, the program claimed world governments were abducting scientists and quietly establishing off-world colonies—forming what some now call a breakaway civilization.
In this episode of Unexplained History, we explore the origins of Alternative 3, the Cold War fears that made it believable, and how a single broadcast blurred the line between fiction, fear, and hidden truth.
We examine the historical context of 1970s Britain, environmental panic, secret space programs, and the long-lasting conspiracy theories surrounding Mars colonization and elite evacuation.
Was Alternative 3 merely an April Fool’s hoax gone wrong—or an early glimpse into the idea of a breakaway civilization operating beyond public knowledge? Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.
