    Ancient stones in Armenia, Karahunj, have many similarities with Stonehenge: a larger, outer circle of stones surrounding a smaller interior circle, though the stones are considerably smaller than Stonehenge's. The largest weigh only 10 tons and are only nine feet tall; an ancient lineage. Karahunj is actually at least 2,000 years older than Stonehenge.

    There is some evidence that both sides were primarily used as burial grounds. There are some 200 shallow graves covered by massive stone slabs on the ground of Karahunj, though, as with burial sites in Stonehenge, the relationship of these graves to the central circles is less than clear. Beyond these surface similarities, little is known, and speculation about the various ways in which Karahunj might have been used rages unabated. One common theory is that the location represents the oldest known astronomical observatory. In support this idea is one odd characteristic of Karahunj, not found in Stonehenge. There are 84 stones which have carefully bored holes at different angles in them, some of which seem to point to various celestial points of significance. The holes are also offered as the reason for the name of the location with kara meaning stones and hunj meaning voices, the presumption being that the wind whistling through the holes in the stones created a distinctive sound.
