Hartashen Megalithic Avenue

Hartashen Megalithic Avenue is a field of basalt menhirs (upright standing stones) arranged in two separate lines that never cross. Each line holds three parallel rows of stones, tilted at an angle rather than set straight up, and nobody has fully explained why they're arranged that way.

For a while the site was written off as a 20th-century defense line — anti-tank obstacles from World War II, the theory went. Recent research has pushed back against that reading. Most specialists now lean toward a much older origin, placing the stones in the Neolithic or Bronze Age, thousands of years before any war reached this plateau. If that dating holds, Hartashen would sit in the same broad category as the Carnac stones in Brittany, France — another vast, unexplained field of standing megaliths whose builders left no written explanation behind.

No firm date has been established either way, and the purpose of the triple-row layout remains open. That's part of the draw here: this isn't a monument with a plaque and a settled story, it's an active question in Armenian archaeology, still being argued over.

The site lies in Shirak region, in Armenia's northwest, roughly 100 km north-northwest of Yerevan as the crow flies. No nearby town is listed for it — check locally for the closest access point before heading out.
