During a recent highway construction project in Czechia, archaeologists have unearthed one of the largest prehistoric burial mounds in Europe.

The find occurred between the villages of Dlouhé Dvory and Lípa, northeast of Prague, along the route of a future motorway near Dohalice. The Department of Archaeology at the University of Hradec Králové announced the discovery in a Facebook post.

The initial clue was an “elongated trapezoidal gutter,” a typical feature of long barrows—ancient burial mounds dating back to the Eneolithic period, specifically the Funnel Beaker culture, between 3800 and 3350 BCE. Further excavation revealed the full extent of the mound: an enormous structure measuring approximately 620 feet (about 190 meters) in length and 50 feet (15 meters) at its widest point. This discovery places it among the longest prehistoric mounds in Central Europe.

An aerial pH๏τograph of the site shows the mᴀssive oval shape of the mound, which, despite its age, remains a significant archaeological find. Unfortunately, the above-ground portion of the mound has been lost, likely due to agricultural activities over the millennia. However, the remaining section has provided a wealth of information.

Archaeologists unearthed two central burials, believed to be for the individuals for whom the mound was originally constructed, as well as 28 additional burials. The graves and the mound are estimated to be at least 5,300 years old.

“The burial mounds were built as monumental funerary objects and as such they contain graves, we call them central burials and ᴀssume that they are the burials of the individuals for whom the mound was built,” the archaeologists explained in their statement. Laboratory analysis will soon provide more precise dating of the burials.

The central burials revealed intriguing details. The first central grave featured an internal pit construction with gutters along the longer sides and post holes at the corners. A ceramic vessel was found as a grave offering, with the body positioned on its left side facing north. The second central burial, lacking an internal structure, also had the body lying on its left side.

In addition to the human remains, the excavation uncovered several artifacts. One grave contained pottery fragments, while another included four flint arrowheads and a flint blade. These artifacts were likely left as offerings and are consistent with grave inventories found at similar sites in Czechia and Poland.

The ancient burial complex is linked to the Funnel Beaker culture, a prehistoric culture known for its distinctive pottery and burial practices.
