Document Summary

The motions of the heavens was studied as a way of warship and divination. Ring of stones in southern sahara desert (6,000 to 6,500 years old) The ring of brodgar (2,500-2,000 bc) in the orkney islands, scotland. Stonehenge, at salisbury plain, england, built in several stages from about. The great pyramid of giza, egypt (about 2500 bc) There is the circular ditch; inside the ditch there is a bank. Aubrey holes which presumably housed initially wooden posts. In the center, there is this arrangement of large stones in the form of a horseshoe. The heelstone is the point when you observe the sunrise on the day of summer solstice, the first day of summer, from the point inside the horseshoe you see the sun rising right above the heelstone. There are astronomical directions and alignments that the stones represent. No one fully knows what the stonehenge was made for.
