The central hollow column is unique in the Balkans, serving both as an architectural support and a light-ventilation system.
The structure is built as a tholos tomb, a type of burial chamber prevalent in the Aegean and Thracian cultures, but uniquely executed in brick here.
Unlike typical tumuli, the interior walls were designed with five horizontal rows of semicircular niches.
The tomb was repurposed as a chapel during the Middle Ages, which helped preserve its structural integrity.
It is located within a man-made mound (tumulus) that was originally covered in earth to conceal the inner chamber.
The Ancient Thracian Tomb (also known as the Thracian Tumulus) near Pomorie is a unique domed structure dating back to the 2nd–3rd century AD. It is considered one of the most significant examples of Roman-era Thracian architecture in Bulgaria. The structure features a distinctive circular central chamber topped by a hollow column that acts as a ventilation shaft. The walls were originally lined with semicircular niches for funeral urns. Its architecture combines traditional Thracian burial mound construction with advanced Roman brickwork techniques. It is widely believed to have served as a heroon, a site for heroic cult worship, rather than a standard tomb. The internal diameter of the dome reaches approximately 11.6 meters, creating a striking acoustic effect. Archaeological evidence suggests it functioned as a mausoleum for a wealthy Thracian family.

Wear comfortable walking shoes with good grip as the interior floor can be slightly uneven.
Bring a light jacket as the interior remains significantly cooler than the outdoor temperature even in mid-summer.
Look up while in the center to clearly see the unique hollow column venting to the sky.
Do not attempt to touch the ancient brickwork or climb on the surrounding mound embankments, as the site is a protected archaeological monument.
