Answer 1

There are probably hundreds of myths and legends about Stonehenge. Various people have attributed the building of this great megalith to the Danes, Romans, Saxons, Greeks, Atlantes, Egyptians, Phoenicians Celts, King Aurelius Ambrosius's, Merlin, and even Aliens.

One of the most popular beliefs was that Stonehenge was built by the Druids. These high priests of the Celts, constructed it for sacrificial ceremonies. It was John Aubrey, who first linked Stonehenge to the Druids. Additionally, Dr. William Stukeley, another Stonehenge antiquary, also claimed the Druids were Stonehenge's builders. Stukeley studied Stonehenge a century later than Aubrey and became so involved in the study of the Druid religion that he himself became one. Through his work he was very instrumental in popularizing the theory that Stonehenge was built by Druids.
