Stonehenge and Sky
Stonehenge, Britain's most celebrated prehistoric monument, is 4,000 years old, dating from c2800-1550 BC. For centuries it has sent writers, painters and every sort of visitor (including photographers) into flights of fancy, for its purpose remains an enigma. Although many of the stones have fallen or disappeared it is still possible, from the center of the circle, to see the sun rise over the Heel Stone (at the entrance) on midsummer's day; there are suggestions that it was constructed as an astrological observatory or a sanctuary for a sun-worshipping cult, or even a combination of the two. The main axis has always been aligned with the midsummer sunrise and Stonehenge must have been a ceremonial center celebrating the sun and marking the seasons. Certainly it was not "built by the Druids", the priesthood of the Celtic peoples who reached Britian in the 3rd century BC, long after the completion of the final phase of building.
Note: Depending on your monitor settings, this shot may or may not appear to be too underexposed to see the silhouette sufficiently. I notice a difference in sharpeness, brightness and contrast all the time between home and work.
