Stonehenge is aligned northeast-southwest, and it has been suggested that particular significance was placed by its builders on the solstice and equinox points.It is unlikely that such an alignment can have been merely accident. Turning 180 degrees, another alignment becomes apparent…..at the precise moment of the winter solstice, the sun sets exactly between the largest sarsen stones. To validate this, we must look at the society of the time. It had become a society now dependent on the seasons, which determined the success of agriculture.
