Ancient solar observatories: Stonehenge
This is Stonehenge. The image shows directions of sun during the day. “The lines on the drawing show the direction and height (altitude) of the sun throughout the day. Thicker and shorter lines mean the sun is higher in the sky. Longer and thinner lines mean the sun is closer to the horizon”, according to Sollumis.com http://www.sollumis.com/. The site is located in the Google Maps. The direction of the sun is given on the summer solstice, choosing an altar at the circle for observation. We see that, at sunrise, the sun is passing near the stone outside the circle.
