  • North Sentinel Island: The Place That Doesn’t Want to Be Found

    On March 29, 2025, a 24-year-old Ukrainian-American YouTuber named Mykhailo Polyakov paddled an inflatable kayak onto the beach of North Sentinel Island, left behind Diet Coke and coconuts, collected sand samples, filmed the encounter, and paddled back out. He was arrested by Indian police within days. Investigation revealed he had conducted reconnaissance of the island in October 2024, had visited other restricted Andaman islands in January 2025 where he illegally filmed members of the protected Jarawa tribe, and had described himself to officers as a “thrill seeker.” The arrest was notable for two reasons. First: it was the first known unauthorized landing on North Sentinel Island since John Allen Chau, a 26-year-old American evangelical missionary, was killed by the Sentinelese with arrows on November 17, 2018, after three attempts to make contact over three days, holding a Bible that a metal-tipped arrow had already pierced on his second visit. Second: the arrest demonstrated that the Indian government’s “eyes-on, hands-off” policy — a five-nautical-mile exclusion zone around the island, enforced by the Indian Navy and Coast Guard — can be breached by a man with a YouTube channel, an inflatable kayak, and a case of Diet Coke.

    North Sentinel Island is approximately 60 square kilometers — roughly the size of Manhattan — covered in dense tropical forest, ringed by coral reefs, located 50 kilometers west of Port Blair, the capital of India’s Andaman and Nicobar Islands territory. It is home to the Sentinelese, who are, by any reasonable definition, the most isolated human population on Earth. They have maintained their isolation for an estimated 60,000 years. They have no known contact with any other human group. Their language is unclassified — mutually unintelligible with both the Jarawa and Onge languages spoken on nearby islands. They have no known agriculture. They have no known metallurgy beyond cold-forging salvaged metal into tools. They have rejected every attempt at contact with sufficient consistency — arrows fired at boats, arrows fired at helicopters, arrows fired at the only anthropologist who successfully made friendly contact (Triloknath Pandit, January 4, 1991, who was eventually warned off when he stayed too long) — that the Indian government officially adopted a policy of non-interference in 2005. The population is unknown. The 2011 Indian census estimated 15 people. Most anthropologists consider that figure unreliable and suggest a range of 50 to 200. Nobody has counted them, because nobody can get close enough to count.

    What we don’t know

    The list of what we don’t know about the Sentinelese is longer than the list of what we do, and the length of that list is itself the most important fact about North Sentinel Island.

    We don’t know what they call themselves. We don’t know what they call their island. We don’t know the structure of their social organization — whether they have chiefs, councils, hereditary leadership, or no formal authority structure at all. We don’t know whether they have religion and, if so, what it looks like. We don’t know their kinship system. We don’t know how they divide labor. We don’t know what stories they tell. We don’t know whether they have music beyond the rhythmic thigh-slapping dance that observers have documented from a distance. We don’t know what happened to them during the 2004 Indian Ocean tsunami, though an Indian Coast Guard helicopter that flew over the island two days after the wave photographed a Sentinelese man firing an arrow at it — which told the world they had survived, and told the helicopter to leave.

    What we do know comes from sporadic and contested observations: they build outrigger canoes for lagoon fishing but do not appear to use them for open-ocean navigation. They hunt wild boar with bows. They gather coconuts, roots, and honey. They build lean-to shelters with slanted roofs, arranged in clusters with small fires outside each structure. They decorate their bodies and weapons with geometric patterns. They use metal — salvaged from shipwrecks on the surrounding reefs — to make arrowheads and adze blades that are larger and heavier than those of other Andamanese tribes. They accepted aluminum cookware left by a National Geographic expedition in 1974. They accepted coconuts from Pandit’s 1991 contact team. They killed the next two people who came ashore — the fishermen Sunder Raj and Pandit Tiwari in 2006, whose boat drifted onto the beach while they slept after poaching in the island’s waters — and the next person after that, John Allen Chau, who came intentionally.

    The Umwelt concept, explored across our Neurozoology course, establishes that every organism inhabits a perceptual world defined by its sensory hardware. The Sentinelese inhabit a cultural and informational Umwelt defined by total disconnection from every other human civilization. They do not know that India exists. They do not know that countries exist. They have no concept of the global economy, the internet, antibiotics, written language, or the legal framework that protects their island. They are protected by laws written in a language they have never heard, enforced by a navy they experience as a threat, governing a territory they have occupied since before the civilization that claims sovereignty over it existed. The island is Indian territory. The Sentinelese have never agreed to this, been informed of it, or had any mechanism by which they could consent or object.

    Why they’re left alone

    The policy is not sentimental. It is epidemiological. The Sentinelese have been isolated for long enough that they almost certainly lack acquired immunity to diseases that are routine elsewhere — influenza, measles, tuberculosis, the common cold. The historical precedent is not abstract: the Great Andamanese, who numbered approximately 5,000 when the British colonized their islands in the 1850s, were reduced to 43 by 1999, primarily through introduced disease. The Onge population dropped from an estimated 672 in 1900 to 96 by the 2011 census. The Jarawa, who maintained hostility toward outsiders until the late 1990s and then began accepting limited contact, have experienced outbreaks of measles and pneumonia that their population — roughly 400 people — can barely absorb.

    Contact with the Sentinelese would, in the assessment of Survival International and the Anthropological Survey of India, risk a die-off that could extinguish the population entirely. The population is small enough — somewhere between 15 and 200 — that a single epidemic could constitute an extinction event. The exclusion zone is not protecting the Sentinelese from modernity. It is protecting them from the common cold.

    The Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation of 1956 established the legal framework. The 2005 policy formalization confirmed that the Indian government has “no intention to interfere with the lifestyle or habitat of the Sentinelese.” In 2018, after Chau’s death, the Ministry of Home Affairs considered reimposing the Restricted Area Permit regime on the island — a system that had been partially relaxed in August 2018 to promote tourism on 29 other Andaman islands, though North Sentinel was never included in the relaxation. The Indian Navy patrols the exclusion zone. Poachers still fish the surrounding waters illegally, catching turtles and diving for lobsters and sea cucumbers. The enforcement is imperfect. Polyakov’s 2025 landing proved it.

    The Great Nicobar threat

    The most significant threat to the Sentinelese may not come from missionaries, YouTubers, or poachers — but from a development project on a neighboring island that demonstrates how selectively the Indian government applies its own protection principles.

    Great Nicobar Island — the southernmost island in the Andaman and Nicobar chain, approximately 140 kilometers south of North Sentinel — is home to the Shompen, another uncontacted or minimally contacted indigenous group of approximately 200-300 people. In 2021, the Indian government approved the “Great Nicobar Island Development Project,” a massive infrastructure scheme that would build a mega-port, international airport, power station, military base, industrial park, and a planned city of 650,000 settlers on the island — an 8,000% population increase. Over three million trees would be felled. The project has been described by Survival International as a “corporate John Allen Chau” — contact forced on an uncontacted people at industrial scale, threatening the same epidemiological catastrophe that the Sentinelese protection policy is designed to prevent.

    The Indian government protects the Sentinelese absolutely and the Shompen not at all. The difference is not legal — both groups are classified as Particularly Vulnerable Tribal Groups under the same regulatory framework. The difference is that North Sentinel Island has no port potential, no military-strategic value, and no development capacity that India wants. Great Nicobar sits at the junction of major shipping lanes near the Strait of Malacca, opposite the Chinese-built Hambantota port in Sri Lanka, and has strategic value that the Indian Navy considers essential to counter Chinese maritime influence in the Indian Ocean. The protection of indigenous groups is absolute where it costs nothing and negotiable where it conflicts with national security objectives.

    Why it’s in the course

    North Sentinel Island is the Off The Map case study that operates on a different axis from every other territory the course covers. Transnistria is a territory that wants to be a state but can’t sustain itself without a patron. Somaliland is a territory that functions as a state but can’t achieve recognition. The micronations are territories that declare statehood without the capacity to exercise it. North Sentinel Island is none of those things. It is a territory whose inhabitants have not consented to be part of any state, have never been conquered, have never signed a treaty, and have maintained their autonomy through the oldest sovereignty mechanism on Earth: they kill anyone who lands on their beach.

    The disputed borders post documented 150+ active territorial disputes defined by competing claims between recognized states. North Sentinel Island has no competing claim. India claims it. The Sentinelese have no concept of India’s claim and no mechanism to dispute it. The dispute — if it is a dispute — is between a modern nation-state and a population that predates the concept of nation-states by tens of thousands of years, communicates in a language no outsider has ever learned, and has expressed its position on the matter of sovereignty with arrows.

    The post that brings North Sentinel Island closest to the course’s other case studies is the question of what happens next. The exclusion zone holds as long as the Indian government enforces it. The Indian government enforces it as long as the island has no strategic value. The Great Nicobar precedent demonstrates that protection is contingent on strategic irrelevance. If the geopolitical calculus changes — if the island’s location becomes strategically relevant, if resources are discovered in the surrounding waters, if the exclusion zone becomes inconvenient — the policy that protects the Sentinelese is a regulation, not a right. It was written by a government the Sentinelese don’t know exists. It can be revoked by the same government.

    This is the kind of place our Off The Map course was built to map — where a population that has lived on the same island for 60,000 years is protected by a law they’ve never heard of, enforced by a navy they shoot arrows at, governing a territory they’ve never consented to being part of, with the protection contingent on the island remaining strategically useless — and the most recent unauthorized contact was a man with a YouTube channel who left Diet Coke on the beach and called himself a thrill seeker.

  • Forbidden Zones: The Places on Earth You’re Legally Not Allowed to Visit

    There is an island in the Bay of Bengal, roughly the size of Manhattan, where the Indian Navy maintains a permanent patrol to ensure that nobody gets within five kilometers of the shore. The island has no roads, no ports, no cell towers, no modern infrastructure of any kind. It is home to the Sentinelese—an indigenous people who have lived there in voluntary isolation for an estimated 60,000 years and have, with remarkable consistency, attempted to kill anyone who approaches. The Indian government has responded to this situation not by trying to change the Sentinelese’s mind but by making it illegal for you to try. Approaching North Sentinel Island is a criminal act under the Andaman and Nicobar Islands Protection of Aboriginal Tribes Regulation of 1956, and the Indian government has publicly stated it will not prosecute the Sentinelese for killing trespassers.

    That is not a hypothetical. In 2018, American missionary John Allen Chau paid local fishermen to take him to the island, where he hoped to convert the tribe to Christianity. He made it ashore. The Sentinelese killed him with bows and arrows. In March 2025, an American YouTuber named Mykhailo Viktorovych Polyakov landed on the beach, blew a whistle, left a can of Diet Coke and a coconut as “offerings,” filmed the whole thing, and left. He was arrested two days later. Police noted he was “lucky he did not make contact otherwise he would have met the same fate.” Survival International, the NGO that advocates for uncontacted peoples, called his actions “reckless and idiotic,” which feels like an understatement for a man who traveled to the one place on Earth where the locals have a documented track record of murdering visitors so he could leave a Diet Coke on the beach and post it online.

    North Sentinel Island is probably the most famous forbidden zone in the world, but it’s far from the only place where you are legally, physically, or practically unable to go. The planet is littered with them—restricted by governments, militaries, treaties, geography, or the simple fact that getting there would kill you. And the reasons a place becomes off-limits are often more interesting than the place itself.

    Area 51, Nevada, United States

    The Groom Lake facility in the Nevada Test and Training Range—universally known as Area 51—is the one everyone knows about and nobody knows anything about, which is the ideal combination for generating decades of conspiracy theories. What we do know: it’s a classified United States Air Force testing facility that has been used since the 1950s to develop experimental and stealth aircraft, including the U-2 spy plane, the SR-71 Blackbird, and the F-117 Nighthawk. What we don’t know: basically everything else. The airspace above it is restricted. The perimeter is monitored by motion sensors, cameras, and security personnel. Warning signs inform you that photography is prohibited and that the use of lethal force is authorized—the kind of signage that really makes you feel welcome.

    The facility’s existence wasn’t officially acknowledged by the U.S. government until 2013, when the CIA released declassified documents about the U-2 program. Sixty years of officially pretending the place didn’t exist while simultaneously stationing armed guards around its perimeter is a very specific kind of bureaucratic performance art. The conspiracy theories—alien technology, reverse-engineered spacecraft, extraterrestrial autopsies—are almost certainly nonsense, but the government’s own commitment to secrecy created the perfect conditions for them to thrive. If you act like you’re hiding aliens, people are going to think you’re hiding aliens.

    The Korean DMZ

    The Demilitarized Zone between North and South Korea is 250 kilometers long and roughly 4 kilometers wide—a buffer strip that has been essentially untouched by human activity since 1953. It is simultaneously one of the most heavily militarized borders on Earth and one of the most pristine wildlife corridors in Asia, because it turns out that landmines and machine gun emplacements are an extremely effective conservation strategy. Red-crowned cranes, Asiatic black bears, and possibly the critically endangered Amur leopard have been spotted in the DMZ, thriving in a landscape that humans have been too afraid to enter for seventy years.

    Tourists can technically visit portions of the DMZ through organized tours from the South Korean side—the Joint Security Area at Panmunjom is the one you see in photographs, where soldiers from both sides stare at each other across a concrete line. But the vast majority of the zone is completely off-limits, laced with an estimated two million landmines, and anybody wandering off the designated tour path would be facing a combination of unexploded ordnance and North Korean border guards, which is not a recreational combination.

    Poveglia Island, Italy

    A small island in the Venetian Lagoon, roughly halfway between Venice and Lido, Poveglia has been closed to the public since 1968 and the Italian government has repeatedly declined to sell or develop it. The island’s history is a greatest hits compilation of everything you’d want in a haunted location. In the late 1700s, it was used as a quarantine station for plague victims—ships arriving in Venice were required to stop there first, and those showing symptoms of the plague were left on the island. By some estimates, over 100,000 people died there during various plague outbreaks, and the island’s soil is reportedly so densely packed with human remains that fishermen in the lagoon occasionally pull up bones in their nets.

    In 1922, the island became a psychiatric hospital, which—given the setting—feels like a creative decision that no modern institutional review board would approve. The hospital closed in 1968, and the island has been abandoned since. Italy’s government has periodically entertained bids to develop it, but access remains restricted, and anyone trying to visit without authorization faces fines. The paranormal tourism industry would very much like Poveglia to be open. The Italian government would very much like everyone to stop asking.

    Svalbard Global Seed Vault, Norway

    Built into the permafrost of a mountain on the island of Spitsbergen in the Svalbard archipelago—roughly 1,300 kilometers from the North Pole—the Global Seed Vault stores duplicate samples of seeds from gene banks worldwide. It’s a backup drive for agriculture. If a crop variety goes extinct due to disease, climate change, war, or catastrophic incompetence, the seeds are here. The vault holds over 1.3 million seed samples from virtually every country on Earth, stored at minus 18 degrees Celsius in a facility designed to remain frozen even if the refrigeration fails, because the permafrost provides passive cooling.

    You cannot visit. The vault is not a museum. It opens a few times a year for depositors—organizations that are adding or withdrawing seeds—and for the occasional delegation of dignitaries who want a photo op in front of the world’s most famous door. The entrance, with its illuminated art installation visible against the Arctic landscape, has become one of the most photographed structures in Norway, which is remarkable for what is functionally a very cold filing cabinet.

    Heard Island, Australia

    A volcanic island in the southern Indian Ocean, roughly 4,000 kilometers southwest of Perth, Heard Island is technically Australian territory but might as well be on another planet. It is one of the most remote places on Earth, dominated by Big Ben—a 2,745-meter active volcano covered in glaciers—and home to colonies of penguins, seals, and seabirds that have never been habituated to humans. The island is a UNESCO World Heritage Site and access requires a permit from the Australian Antarctic Division, which is granted almost exclusively to scientific researchers. The weather is, by all accounts, spectacularly hostile—constant gale-force winds, temperatures rarely above freezing, and seas that make the approach by boat genuinely dangerous.

    The restriction isn’t about secrecy or military sensitivity. It’s about preserving one of the last places on Earth where a complete subantarctic ecosystem functions without any human footprint. No introduced species, no infrastructure, no trails, no garbage. The Australian government’s position is essentially: we have one of these and we’re not going to let anyone ruin it.

    Lascaux Cave, France

    The Lascaux cave paintings in the Dordogne region of southwestern France—created approximately 17,000 years ago—are among the most important archaeological sites on Earth. They depict horses, aurochs, deer, and abstract symbols in pigments that have survived for seventeen millennia. The cave was opened to the public in 1948 and received roughly 1,200 visitors per day through the 1950s. By 1963, the carbon dioxide, heat, and humidity generated by all those human bodies had caused visible damage to the paintings—green algae, white calcite deposits, and black fungal growth on surfaces that had been stable for 170 centuries until tourists showed up.

    The cave was closed to the public in 1963 and has remained closed since. Even the researchers who monitor the paintings are limited in how often and how long they can enter. The French government built Lascaux II, a precise replica of the two most famous chambers, about 200 meters from the original, and later Lascaux IV, an even more elaborate facsimile. You can visit a copy of the cave. You cannot visit the cave. The originals sit in climate-controlled darkness, preserved by the absence of the very species that created them.

    What forbidden zones actually tell us

    The through-line across these places—and the dozens of others like them, from Mezhgorye in Russia to the Heard Island volcano to the closed military cities of the former Soviet Union—is that the reasons for restricting access are almost always more revealing than whatever’s behind the fence.

    North Sentinel Island is forbidden because of an unresolved collision between indigenous sovereignty and the modern world’s inability to leave anything alone. Area 51 is forbidden because military secrecy, once established, takes on institutional momentum that outlives its original justification. The DMZ is forbidden because two countries that never signed a peace treaty have been in a frozen standoff for seven decades, and the buffer zone between them has accidentally become an ecological paradise. Lascaux is forbidden because we loved something to death and had to wall it off from ourselves. Svalbard is forbidden because someone had the foresight to build a backup plan for civilization and the wisdom to not turn it into a tourist attraction.

    These aren’t just places you can’t go. They’re places that tell you something about how humans interact with the things they find most valuable—whether that’s a species, a secret, a painting, or a seed.

    We cover forbidden zones, disputed territories, unrecognized states, and places erased from official maps across our Off The Map: A Global Atlas of Non-Existent Places course—a full atlas of the places the world doesn’t quite know what to do with.
