Just a few miles northwest of Bulgaria’s capital Sofia lies the small village of Tsarichina. For most Bulgarians, this was an unknown place until 1990, when it became the center of one of the country’s most mysterious and controversial episodes in modern history. What started as a secret military excavation soon became surrounded by rumors of aliens, ancient artifacts, and a tunnel to the origins of humanity. The story of the Tsarichina Hole is Bulgaria’s answer to Area 51—and possibly even stranger.
A Nation Searching for Identity and Hope
The unlikely tale begins in the chaotic period after the fall of communism in Bulgaria. Amid political and economic collapse, many people lost their faith in the future. In this climate of uncertainty and desperation, both visionaries and opportunists found a fertile ground for influence.
It was in this atmosphere that a group of psychics claimed to receive messages from other dimensions. These messages pointed to the village of Tsarichina as the site of a monumental discovery. The psychics contacted the Bulgarian military and convinced them that something extraordinary lay beneath the ground: the treasure of Tsar Samuil, a hermaphroditic being, an ancient humanoid—or perhaps evidence of humanity’s extraterrestrial origins.
Operation Sunray: The Mysterious Dig
On December 6, 1990, a classified military operation began. Soldiers and excavation equipment were dispatched to Tsarichina. The area was fenced off and guarded 24/7. The excavation continued for nearly two years. A 160-meter-long and 70-meter-deep tunnel was dug. What they were looking for changed over time—from historical treasures to humanity’s lost DNA.

Strange phenomena were reported almost immediately. According to multiple witnesses, mysterious flashes of light, electromagnetic fields, and bizarre sounds were observed. A silvery chamber with unknown symbols and a stone slab with untranslatable inscriptions were said to have been discovered. Psychic Elisaveta Loginova, one of the key figures in the project, claimed to be in contact with an extraterrestrial being she called “Amonia.” She later wrote a book about her experiences: Tsarichina: Fateful Contact.
It didn’t take long for the project to gain a reputation for being more than just a scientific search. Soldiers and engineers began to report mental stress, hallucinations, and strange dreams. According to some accounts, guards fired bullets at invisible forces that could not be harmed. Others claimed they encountered a powerful energy that repelled them from certain areas in the tunnel.
Loginova claimed that the site was guarded by a force beyond human understanding. She believed the Tsarichina Hole was a portal to another dimension—a link not only to our genetic origins but also to a deeper spiritual truth.
An Abrupt End and Tragic Consequences
On November 19, 1992, the project was suddenly shut down. Officially, it was due to lack of funding. However, no clear financial records ever emerged, despite the operation’s extensive costs. Shortly after, the tunnel was filled with concrete.
Soon after, one of the psychics took their own life. A military officer involved in the project also died by suicide three years later. These tragic events led some to believe that something terrible happened in the tunnel—something the government wanted to hide.
Tsarichina Hole Today
Today, nothing remains of the original hole. Yet the site still attracts conspiracy theorists, spiritual seekers, and UFO enthusiasts. A simple stone inscribed with “Обект Дупката” (Object: The Hole) marks the location. Nearby is a themed restaurant called “The Hole” that plays off the mystery.
Although no verifiable evidence has emerged of alien contact, the Tsarichina Hole has become a cultural symbol of the Bulgarian people's search for meaning during a time of collapse and uncertainty.
Cultural Impact and Pop References
In recent years, several documentaries, podcasts, and films have explored the mystery of the Tsarichina Hole. One of the most notable is the 2024 film Triumph, a dark satire depicting a psychic guiding a group of soldiers on a dig that promises to “make Bulgaria great again.” The film explores themes of national identity, desperation, and humanity’s hunger for the supernatural.
Several podcasts have also covered the topic. Shows like Astonishing Legends and The Conspirators have released episodes delving into the strange reports from Tsarichina, interviewing Bulgarian witnesses and researchers.
What Really Happened in Tsarichina?
No one knows for sure. Some believe it was a psychological experiment or a desperate attempt to create hope in a nation recovering from authoritarian rule. Others see it as a mass delusion, a collective hallucination. And some still believe it was a genuine attempt to understand humanity’s true origin—and its connection to the stars.
What we do know is that the Tsarichina Hole has become a symbol of how humans, in times of crisis, turn to mystery. It’s a place where fact and belief collide, where science and spirituality meet—and where the most important thing might not be what actually happened, but what we choose to believe.

This is the insane true story of the Tsarichina hole, one of the most bizarre mysteries to have ever come out of Europe.
