Stonehenge Decoded

Modern archaeologists have documented a plausible theory about Stonehenge. For 5,000 years, the purpose of this monument has remained a mystery, but archaeologists have uncovered a theory to explain this architectural riddle. Here is the National Geographic site for Stonehenge Decoded. National Geographic aired a 2-hour documentary in June 2008. See Archaeoastronomy and Stonehenge for additional theories.
