So Now You Know
Stonehenge is mentioned within Arthurian legend. Geoffrey of Monmouth said that Merlin the wizard directed its removal from Ireland, where it had been constructed on Mount Killaraus by Giants, who brought the stones from Africa. After it had been rebuilt near Amesbury, Geoffrey further narrates how first Ambrosius Aurelianus, then Uther Pendragon, and finally Constantine III, were buried inside the ring of stones.
