Arthur's roundtable at King's Knot, Scotland?

Archaeologists at King's Knot in Stirling, Scotland have discovered a "circular feature" that some believe might be the fabled round table of King Arthur.

The flat-topped central mound, re-landscaped in the 17th century, has been linked for generations to the round table. Now, a non-invasive investigation of the site has discovered "a round feature on the site that pre-dates the visible earthworks."
