Note 207 — THE BOOK OF THE DEAN OF LISMORE. (continued 2)
Thomas Maclauchlan translation
Castle Sween is an ancient stronghold at the mouth of Loch Sween in Knapdale, said to take its name from Sween of Argyle, who flourished in the thirteenth century; but the Irish annalists make mention of it at a much earlier period. It was probably a stronghold of the Dalriadic monarchs.
