[Castle Treen and its Legends.]
"I cannot tell how the truth may be,
I say the tale as 'twas said to me."
Scott.
OLD traditions say that the headlands of Castle Treen, or rather Trereen, on which the Logan Rock carn and adjacent crags stand, was raised out of the sea by enchantment. This portion of the stronghold, enclosed by the inner line of defence, running directly across the isthmus, is generally spoken of as The Castle, and that between it and the outer or landward embankments is usually called Treen Dynas.
The Key of the Castle.
It is not known what powerful magician raised this giant's hold, though it was believed that its security depended on a magic stone called "the key of the Castle," respecting which Merlin had something to say, as well as about many other remarkable stones in the neighbourhood. Castle Treen, however, must have stood where it is long before Arthur and his magician visited West Cornwall.
