If real, you would expect the Round Table to be situated somewhere in Manann/Manau. Not of course a table, but something to which the name Round Table became attached.

Standing at the foot of the rock on which Stirling Castle stands, is an impressive earthwork structure known today as The Kings Knot, but to which the name Round Table became attached as far back as 1370 AD. It was certainly added to and altered by the Stuart Monarchs in later centuries, but nevertheless existed before their time.
