It must somehow involve the sky?
Some archaeologists believe that the circles have been constructed in relation to the midsummer sunrise, or to record the movements of the sun and moon acting as markers in a calendar to identify certain lunar, solar or stellar events.
Three of the stone rows point to sunrise at the solstice and another appears to be aligned towards a lunar maximum.
The stones speak of ancient rituals and to a people who understood astronomy. When you visit this ancient site look up in wonder at the sky and reflect, that the people that built the monuments observed the same sky, sun, moon and stars.
Could this have been the first observatory in Davagh Forest?
