Hlyabovo dolmens, Megalithic burial chambers in Hlyabovo, Bulgaria.

The Hlyabovo dolmens are stone burial chambers built from large stone slabs forming walls and roofs located in the Sakar Mountains. The structures consist of carefully stacked stones that create underground chambers which have survived for thousands of years.

These burial chambers date from the early Iron Age between 1050 and 500 BC and represent the first examples of monumental tomb architecture in Bulgaria. They reflect how the Thracians buried their dead during this period and how their society was organized.

Local people call the rock-cut chamber at Evdzhika a dolmen-like site; Georgi Bonchev published it in 1901, and his photographs show a front slab that is now missing. Grooves where the slab fitted are still visible in the rock, and small man-made hollows mark the inner walls.

Visitors can reach the main dolmen through a marked path in the Nachevi Chairi area, where several well-preserved structures remain visible. Access is relatively straightforward, but sturdy footwear is recommended as the terrain is uneven.

At the Nachevi Chairi dolmen, excavations in 1976 uncovered a second dolmen attached to its side, where the first preserved remains of a burial in a Bulgarian dolmen were documented. The site also revealed a facade wall and a rich assemblage of archaeological material.
