Rumored to be among the world’s most classified subterranean networks, the Metro-2 is believed to lie beneath the equally captivating Moscow Metro. It is said to have served as a clandestine transit route for Soviet Union elites.
Speculations suggest it might still be in use today. Beyond its role as a hidden rail network, some experts propose that a sprawling, multi-level underground complex exists beneath Moscow, potentially reaching depths of up to 15 floors. Could these assertions hold any truth?
10. A Legacy of Covert Underground Initiatives

Centuries before the Moscow Metro was conceived, Russia had already established a tradition of constructing hidden subterranean sites and structures, dating back hundreds of years.
One notable example is a concealed vault beneath the Kremlin that once stored hundreds of ancient manuscripts, which vanished mysteriously during the 1500s. These were believed to be priceless texts from the Byzantine library. Whether they were destroyed or hidden away in an undisclosed location remains a topic of speculation.
In the 16th century, Ivan the Terrible orchestrated his own secret underground network, utilizing it to detain, torture, and execute those who opposed him.
A particularly unsettling aspect of these underground torture systems is the grim fate of the workers who built them. Historical records indicate that those involved were taken underground and killed to ensure the secrecy of these operations.
9. The Underground Is Constructed From Materials of Numerous Historic Buildings

It is believed that a significant portion of the materials used in the construction of the Moscow Metro and the rumored Metro-2 system originated from the opulent structures once owned by the Russian royal family.
While plans for an elaborate underground network had been in discussion for years, actual construction only commenced in the early 1930s. Under Stalin’s direct command, materials were sourced by demolishing historic buildings, which were stripped of all usable components.
This approach was partly justified by the idea of redistributing wealth from the elite to the public—at least in theory. In practice, however, it was more about exploiting easily accessible resources, revealing the underlying motives of such ideological claims.
8. A Significant Portion Was Built Manually

A significant portion of the Moscow Metro's construction was carried out manually by Soviet citizens. Officially, this was attributed to a shortage of proper machinery and was portrayed as a testament to the dedication of the Soviet people.
However, it is widely believed that many of these workers were political dissidents. While this is not officially documented, historical context suggests that such forced labor likely occurred, lending credibility to these claims.
Those who assert the existence of the covert Metro-2 network claim that only a chosen few were permitted to work on these hidden lines. These individuals were undoubtedly aligned with the state's ideology, ensuring no dissent would arise.
Regardless of who labored on which sections of the underground systems, the work was grueling, exhausting, and relentless.
7. The Networks May Have Been Built Out of Paranoia

While the Moscow Metro had its official justifications, the Metro-2 system was likely born out of sheer paranoia.
After World War II, a quiet resentment toward Stalin, his ideology, and his regime simmered among the Soviet population. This discontent had been growing for years, hidden beneath the surface.
Stalin harbored genuine fears of assassination. Many believe the Metro-2 network and its associated underground living spaces were designed to provide an escape route for Stalin and his loyalists in the event of a revolution or a direct threat to his life.
It stands to reason that only a handful of trusted individuals would have been informed about this network, let alone granted access to it.
6. Access to Metro-2 Was Restricted to Authorized Personnel Only

As anticipated, only individuals with the highest level of security clearance could access the Metro-2 system, effectively limiting entry to the elite. These restrictions reportedly remain in place today, albeit unofficially.
Numerous researchers have sought permission to explore the rumored tunnels, but nearly all requests have been denied. This raises questions—why deny access to something that supposedly doesn’t exist?
Reports suggest that as recently as 2008, the Moscow Metro trade union was quietly recruiting specialized drivers for “classified routes.” While these could have been for official government purposes, the secrecy fuels speculation.
Given the persistent rumors surrounding Metro-2, it’s understandable why researchers draw connections. If the claims hold any truth, what clandestine operations might be unfolding beneath Moscow today?
5. Exclusive Lines Operate with Limited, Compact Trains

While these reports should be approached with skepticism (as with all Metro-2 claims), the idea of exclusive routes and “short trains” is intriguing. These measures likely prioritize safety and secrecy, often featuring just one passenger car with limited capacity.
Researcher Yuri Zaitsev asserts that four secret lines remain operational today, linking crucial sites across Moscow and enabling access to other significant locations. (The dotted lines in the image above are believed to represent these covert Metro-2 routes.)
Former government minister Mikhail Poltoranin seemingly supported these claims, stating, “I am aware that Metro-2 has extensions reaching the suburbs, allowing leadership to evacuate from a nuclear strike’s epicenter.” He also described the network as “extensive” and capable of “sheltering numerous individuals.”
4. Numerous Former Politicians and Defectors Have Acknowledged Metro-2’s Existence

Following the collapse of the Soviet Union—and in some instances, even earlier—several high-ranking officials have publicly affirmed the reality of Metro-2. While it’s tempting to dismiss these accounts as conspiracy theories, the consistency of these claims makes them noteworthy.
For instance, former information minister Alexander Muzykantskiy stated that the vast underground network was “built to guarantee the uninterrupted functioning of top military and political leaders during armed conflicts, including nuclear warfare.”
Oleg Gordievsky, a Soviet defector, made even more startling assertions. He revealed, “You are still unaware of the KGB’s greatest secret: a massive underground city, an entire network of such facilities. But they will never reveal it to you. Never, of course.”
Even today, many of these assertions originating from the former Soviet Union are equally fascinating and exasperating, as they seem riddled with misinformation.
3. Numerous ‘Vacant Lots’ Serve as Gateways to the Underground

Whispers and theories propose that hidden access points to this subterranean system are concealed within seemingly “incomplete” structures scattered across Moscow. Intriguingly, there are multiple such sites.
These empty spaces vary widely—ranging from half-built hospitals to parking lots and various unfinished constructions. Local lore in Moscow suggests that some or all of these derelict buildings provide entryways to this covert underground network.
Notably, many of these rumored secret entrances often draw undesirable groups, including drug dealers and satanic cults. They also become temporary shelters for the homeless seeking a safe place to rest.
Whether any of these individuals have stumbled upon these hidden entrances remains unknown. If you were to explore Moscow’s secluded areas, you might be astonished by what you uncover.
2. Ramenki-43: A Subterranean City Beneath the Surface

One of the most bizarre and captivating rumors about the Metro-2 system is the alleged existence of a “city beneath the city” in Ramenki, known as Ramenki-43. This covert city was reportedly constructed to shelter the Soviet elite in the event of nuclear war or other catastrophic events.
Several researchers and whistleblowers have shared insights about this secret underground city. A former KGB officer even discussed it with Time magazine, revealing that the facility could accommodate approximately 15,000 people. The city was multi-leveled and linked to other secret sites across Moscow.
Interestingly, the rumored subterranean city is also reachable through a deserted plot close to Moscow State University. These supposed hidden entry points are reportedly scattered throughout Moscow.
1. They Provided Access to Highly Classified Underground Shelters

As we’ll explore shortly, the Metro-2 line may conceal far more than just a railway system. For instance, numerous underground shelters are thought to be located beneath and around it, all constructed with the intent of surviving a nuclear catastrophe.
However, these shelters seem to have been more than just basic emergency spaces. According to many investigators, they were outfitted with extravagant amenities. Additionally, they were built to support extended stays, potentially lasting several months or even years.
According to whistleblowers and defectors, these shelters were reportedly reserved solely for high-ranking, loyal members of the Communist Party and the Politburo. Furthermore, each individual was permitted to bring their entire family into what essentially functioned as opulent subterranean residences.
