Armenia’s prehistoric observatory — older than Stonehenge
On a rocky plateau above the Vorotan River valley, 5 km northwest of Sisian in Syunik province, stands one of the most intriguing prehistoric sites in the Caucasus. Karahunj — also known as Zorats Karer, meaning “Army Stones” in Armenian — is a field of approximately 223 basalt standing stones, most between 1 and 3 metres tall, arranged in what appears to be a deliberate astronomical pattern.
The name “Karahunj” echoes the English “Stonehenge” — both words arguably derive from proto-Indo-European roots for “stone” and “voice” or “hanging” — though the resemblance is disputed by linguists. What is less disputed is the age of the site: radiocarbon dating and comparative analysis suggest the stones were erected between approximately 5,500 and 3,500 BCE, making the complex potentially 1,500 years older than the Wiltshire monument it is often compared to.
The feature that distinguishes Karahunj from other Armenian standing stone fields is the holes. About 84 of the stones have a circular bore hole carved through their upper portions. Astrophysicist Paris Herouni, who conducted the most detailed study of the site in the 1990s and 2000s, argued that the holes were used as sighting tubes for astronomical observation — specifically for tracking the rising and setting of the sun, moon, and certain stars at significant points in the agricultural calendar. The debate among archaeologists continues, but the holes are real and their purpose remains unexplained by alternative theories.
Getting there
From Yerevan: 200 km via M2 highway through Vayots Dzor. Allow 3 hours 30 minutes by car. The site is 5 km northwest of Sisian on a signposted road. A rough track leads from the road to the stone field; a standard car can manage it in dry conditions.
From Goris: 30 km north on the main road through Sisian. Allow 35–40 minutes. This makes Karahunj an easy half-morning excursion from a Goris overnight base.
By tour: several guided tours include Karahunj as part of a Syunik circuit combining Noravank, Tatev, and Goris. Dedicated Karahunj archaeology tours are rare but can be arranged through specialist operators in Yerevan.
Public transport: the nearest marshrutka stop is Sisian (5 km). From Sisian, a local taxi to the site costs approximately 1,500–2,000 AMD.
What to see
The stone field
Walk among the standing stones themselves. The arrangement consists of a central oval enclosure approximately 45 metres in diameter, with two “arms” of stones extending to the north and northeast. The individual stones vary in size from knee-height to taller than a person. Many lean at angles; some have fallen. The atmosphere — especially in early morning before tour groups arrive — is genuinely ancient.
Look for the bored holes: roughly a third of the upright stones have circular openings in their upper sections, approximately 5–7 cm in diameter. Hold your eye close to one of the holes and you will find yourself looking at a precise point in the sky. Herouni and other researchers have mapped alignments to specific astronomical events; the directions vary between stones.
The burial mounds
Near the stone field, several Bronze Age burial kurgans (mounds) have been identified. The area was clearly a significant ceremonial landscape for thousands of years.
Photography and the landscape
The plateau setting is exceptional. To the west, the Vorotan River valley drops away below. The basalt stone outcrops and sweeping highland views provide a dramatic backdrop for the stones themselves. Early morning and late afternoon light casts long shadows across the field; overcast conditions actually produce flattering, even illumination for archaeology photography.
Combining Karahunj with nearby sites
Karahunj is most naturally combined with Sisian town (5 km, a useful lunch stop and base), Goris and Khndzoresk (30 km south), and Tatev monastery (65 km south via Goris). A logical Syunik day from a Goris base: morning at Khndzoresk, midday at Karahunj/Sisian, afternoon at Tatev.
From the north, visitors coming from Yerevan can incorporate Karahunj into the drive south without significant detour — the site is directly on or near the M2 highway route to Goris and Tatev.

Practical tips
- Entry fee: a small admission fee (approximately 500–1,000 AMD) may be charged at the site. Check locally — the fee structure has varied in recent years.
- Footwear: the plateau is uneven. Wear shoes suitable for walking on rough basalt and dry grass.
- Weather: the plateau is exposed. Wind can be strong even in summer. Bring a layer.
- Time of day: sunrise and sunset are worth the effort if you are basing yourself in Sisian or Goris — the light on the stones is exceptional at these times and the site is empty.
- Signage: on-site interpretation panels have improved in recent years but remain limited. A local guide adds considerably to the visit.
- Combined with Sisian: the Sisian History Museum has a small but interesting display on Karahunj and the prehistoric archaeology of the region.
Frequently asked questions about Karahunj
Is Karahunj really older than Stonehenge?
Archaeological dating suggests the Karahunj stones were erected approximately 5,500–3,500 BCE, compared to Stonehenge’s main construction phase of 3,000–1,500 BCE. If the dating is correct, Karahunj predates Stonehenge by at least 1,500 years. The comparison is frequently made in Armenian tourism materials. As with all prehistoric archaeology, exact dating involves some uncertainty.
What do the holes in the stones mean?
The approximately 84 stones with bore holes remain a genuine archaeological mystery. Astrophysicist Paris Herouni’s hypothesis — that they served as sighting tubes for astronomical observations, aligning with the rising and setting of the sun and specific stars — is the most developed interpretation. Other researchers have proposed that the holes had ritual significance. No consensus has been reached, which makes Karahunj one of the more intellectually engaging prehistoric sites in the region.
Why are there two names?
“Karahunj” is the name popularised by Herouni’s astronomical research, derived from Armenian words often translated as “stones with voice” or linked to “Stonehenge.” “Zorats Karer” is the older local name meaning “Army Stones” in Armenian, referring to the standing stones resembling a mass of soldiers. Both names are used; official Armenian tourism materials tend to use Karahunj.
How long does a visit take?
Walking the full stone field carefully, reading the interpretation panels, and exploring the surroundings takes 1.5 to 2.5 hours. A focused photography session at golden hour could justify 3 hours. A rushed transit visit — if you are driving the Syunik circuit — can be done in under an hour.
