In the early 1990s, a mysterious military operation in the small Bulgarian village of Tsarichina became one of the country’s most controversial and enigmatic events. Operation Sunray, conducted between 1990 and 1992, combined elements of military secrecy, ancient history, and what many consider to be a massive waste of public resources.
A Royal Mystery Unfolds
Just 30 kilometers from Sofia, Tsarichina’s hillside became the focus of intense military activity. The official narrative spoke of geological surveys and military research, but whispers of a far more intriguing objective spread quickly: the search for King Samuil’s legendary royal treasure, hidden during Bulgaria’s golden age. This treasure, believed to include the crown jewels of the First Bulgarian Kingdom, vast quantities of gold, and priceless historical artifacts, became the unofficial heart of the operation.
Objectives
The officially stated objectives of Operation Sunray included:
- Investigating anomalous geological formations
- Conducting deep excavation work for undisclosed military purposes
- Searching for alleged underground structures of unknown origin
- Gathering data on unexplained electromagnetic phenomena reported in the area
However, unofficial sources suggest additional objectives:
- Searching for ancient artifacts of strategic importance
- Investigating potential alien technology, as claimed by some witnesses
- Exploring underground tunnels supposedly dating back to Thracian times
- Seeking advanced military technology allegedly hidden during World War II
