English: Craig y Forwyn The maiden's rock? There must be a story attached...... A seemingly natural outcrop, the extensive scree of debris and remains of benching with produced limestone boulders indicate that this too is extensively quarried. The local Carboniferous Limestone has always been a valuable asset, both for building stone and agricultural lime. The narrow gap of the Dulas valley as it cuts through the coastal hills is a natural point at which to exploit these mineral riches.
