In 1972, during excavations in Varna's Western Industrial Zone, excavator operator Raycho Marinov accidentally uncovers an ancient necropolis—a burial complex hidden beneath the ground. At a depth of 1.40 meters, he discovers a large quantity of gold and other valuable items. This unexpected archaeological phenomenon unfolds on the northern shore of Lake Varna, near the water's edge.

Across an area of approximately 3000 square meters, a total of 294 graves have been unearthed, containing significant wealth and golden adornments. These findings date back to the end of the Stone Age and the beginning of the Copper Age. Despite partial deterioration over time, these discoveries provide crucial insights into ancient civilization and the lives of people during this period.

In 1974, Japanese scholars conducted radiocarbon dating on the items from the necropolis, determining that they were created between 4600 and 4200 BCE. This makes them one of the earliest examples of gold processing on a global scale.

The discovered gold items, totaling 6.5 kilograms and over 3000 pieces, represent a grand treasure. The gold is nearly pure, with a purity of 23.5 carats, indicating the high standards of goldsmithing skills and refining technologies used by ancient goldsmiths.

Scientific studies also reveal that the necropolis represents a site of significant social and cultural importance. It provides insights into the social structure and communal practices of ancient communities that inhabited this region in the distant past.

While the fate of this ancient civilization remains a mystery to modern researchers, the archaeological discoveries from the necropolis endure as a valuable window into the past. They unveil the skills and traditions of ancient communities, as well as important aspects of their culture and history.
