Stonehenge is most likely an observatory for following the sun through the seasons. It is a monumental shrine to the sun. Stonehenge"s heel stone is aligned to the summer solstice sunrise. The sun used to hit right next to the heel stone and that didn"t make sense. *the reason being is because the sun"s daily arc in the northern hemisphere is shifted towards the south. The noon sun means that the sun is at its highest point in the sky and it also means our location is directly facing the sun"s direction.
