Adam’s Calendar: Oldest Megalithic Site in the World

Adam’s Calendar is controversially suggested to be the oldest man-made structure in the world.  Sometimes referred to as “African Stonehenge”, it predates both Stonehenge and the Great Pyramid of Giza by tens of thousands of years.  Located in Mpumalanga, South Africa it is a standing stone circle about 30 meters in diameter and has been estimated by some accounts to be more than 75,000 years old. Various astronomical alignments have been identified at the site and it is possibly the only example of a completely functional, mostly intact megalithic stone calendar in the world.

The site is aptly named Adam’s Calendar because the stones are placed to track the movement of the sun, which casts shadows on the rock.  It still works perfectly as a calendar today by following the shadow of the setting sun, which is cast by the taller central monolith onto the flat stone beside it.  This remarkable calendar was originally a large circular stone structure resembling Stonehenge and in the center of the ‘circle’ are two upright stones which are said to have been carved.  Its original shape is still clearly visible from satellite images.  The stones are all dolomite, weighing up to 5 tons each, and are said to have been transported from a distant site.  It should be noted that the area surrounding Adam’s Calendar is extremely rich in gold.
