Karahunj / Zorats Karer
On a high plateau in southern Armenia, 223 basalt standing stones — many pierced with mysterious round holes — form one of the oldest megalithic complexes in the world, potentially predating Stonehenge by thousands of years and sparking fierce debate about whether Neolithic Armenians built a systematic astronomical observatory.
At a glance
Karahunj (Armenian: speaking stones or stone army) — also known by its Turkic-derived name Zorats Karer (army stones) — is a megalithic complex near the town of Sisian in the Syunik Province of southern Armenia, at an elevation of approximately 1,770 metres above sea level. The site consists of 223 large basalt standing stones arranged in a rough oval approximately 140 × 70 metres, with two arms of stones extending north and south. Carbon dating of human remains from associated burial cysts establishes human activity here from at least 5500 BC, making it one of the oldest megalithic sites in the world. Whether the monument as a whole was built at that date, or whether the stones were raised later over an already-ancient cemetery, remains an open question in archaeology.
History and archaeology
The site was largely unknown outside Armenia until 1994, when Armenian astrophysicist Paris Herouni began systematic archaeoastronomical studies that brought Karahunj to international attention. Herouni’s team surveyed the stone orientations, measured the angles of the drilled holes in 84 of the standing stones, and claimed to identify precise alignments with solar and lunar events — solstice and equinox sunrises and sunsets, and lunar standstills — arguing that the holes functioned as astronomical sighting devices pointing to horizon positions of celestial phenomena. Herouni concluded the site was a working observatory constructed around 5500 BC, and proposed the name Karahunj as the indigenous Armenian name that gave rise, via migration, to Stonehenge in England — a claim not accepted by mainstream linguistics.
The archaeological record is more modest: excavations have revealed stone cist graves (box-like burial chambers built from stone slabs) associated with the stones, containing skeletal remains, pottery, obsidian tools, and bronze artefacts spanning from the Chalcolithic through the Bronze Age and into the Iron Age — suggesting the site was used and re-used over many millennia. Whether the arrangement of the standing stones themselves encodes astronomical information, or whether some alignments are coincidental in a monument with 84 holes and a horizon full of potential celestial targets, remains debated among archaeoastronomers.
The stones and their holes
The standing stones vary considerably in size, ranging from about 0.5 to 3 metres in height, and are of local basalt — a dark, dense volcanic rock typical of the Armenian plateau. Approximately 80 of the 223 stones are still standing; the remainder are fallen or lean at angles. The most remarkable feature of the site — and the one that generated the astronomical hypothesis — is the round hole drilled horizontally near the top of 84 stones, each approximately 5–8 centimetres in diameter and passing cleanly through the stone. If these holes were pointed at the horizon and a person sighted through them, they would see a narrow circle of sky at a specific azimuth and altitude.
Herouni’s analysis identified alignments between specific stones and sunrise/sunset at the summer and winter solstices, equinoxes, and other significant astronomical dates. Critics note that with 84 holes pointed in varied directions across a full 360-degree horizon, statistical alignment with multiple celestial events is inevitable without any deliberate design. The question of whether the pattern of alignments is significantly non-random has not been definitively resolved.
Key facts
- Date: Human activity from c. 5500 BC; monument construction date uncertain
- Number of stones: 223 total; 80 still standing
- Site dimensions: Oval c. 140 × 70 m, with north and south arms
- Stones with holes: 84 (holes approx. 5–8 cm diameter)
- Altitude: c. 1,770 m above sea level
- UNESCO status: Nominated; on Armenia’s tentative UNESCO list
- Protected status: Historical and Cultural Monument of Armenia
Setting and landscape
The site occupies a broad plateau above the Vorotan River gorge, with wide views in almost every direction. To the east and north-east, the snow-capped peaks of the Zangezur range (part of the Lesser Caucasus) form the backdrop. The plateau itself is a high-altitude steppe of dry grass and basalt outcrops, dramatic in its emptiness. At sunset, the dark stones against the pale sky and distant mountains create one of the most visually powerful prehistoric landscapes in the South Caucasus. The site is open-air and unfenced, accessible year-round, and rarely crowded outside the summer peak.

Getting there
Sisian is on the main north–south highway M2 between Yerevan (225 km) and the Iran border at Meghri. From Yerevan: marshrutka (minibus) services depart from the Kilikia bus station daily. The drive takes approximately 3.5–4 hours. From Goris (46 km north): taxi or local transport. From the Tatev Monastery cable car (40 km south-west): combine in a day trip by car. There is no train service to Sisian.
