There are those that believe that real King Arthur was a Scottish leader named Artorius, a historically documented son of King Aidan. This Artorius was the prince of the Kingdom of Manaan in the late 500s and died in the Battle of Manau, which the Annals of Ulster say occurred in 582. This could just be related to Arthur's final battle of Camlann.
Artorius' Camelot is supposed to have been Roman fort on the Antoinine wall known as Ad Vallum. To the post-Roman Scots, this fortress was known as Camelon, a name today is given to a small town outside of Falkirk.
Ad Vallum is now a golf course. The connection between Camelot and Camelon appears to be based on the similarity of the names . Given Camelot is first mentioned in Chrétien de Troyes's Lancelot, it would seem unlikely that Camelon was what Troyes had in mind when he dreamed up the notion.
