Statistical Account 1791-99 11 25 “With in the same farm [Torrs] there is a remarkable cave, in the precipice of the sea shore. From the entrance to the furthest end measures 60 feet, but the height is unequal. It is narrow at the mouth, then gradually widens, rising in height to 12 feet or more; again it contracts, and at the end of 60 feet terminates. The door had been originally built with stones, and had a lintel, which is now fallen down, and buried under the rubbish. The cave itself is a work of nature. From its sequestered and difficult access, amidst rocks and precipices, it appears to be a hiding place in ancient times. It was not improbably some Druidical cave”.
