Some of these stone structures are circular, with radial lines of stones. These circles have been also compared with Stonehenge. Therefore, we can ask ourselves, are these solar observatories too, as Stonehenge is.

I used a software for the solar energy applications to see the direction of sun on sunrise and sunset of solstice. It seems that there is a good agreement. Therefore, the Syrian stone circles are probably the Stonehenges of Middle East.
Circles and lines!

it is told that "He (David Kennedy) explains that they come in a huge variety of forms, some being ‘kites’, structures that funnelled animals, some being seemingly random meandering lines of stone and others being rectangular. None are believed to be aligned with the stars, which has added to the mystery surrounding their purpose." Well, in my opinion it is not so.
