Went up to Chamber today...very difficult to gain access to the area round Cuff Hill, nearly impossible apart from the fact that my companion and I are fairly fit, and were able to climb the 10 ft deer fence surrounding Cuff Hill. The area has been planted with saplings.....no idea who you would approach about entry but talk in the Gateside Pub was that an Irishman owns the land....Good luck ye all...apart from that the area is sublime, water, birds, spring...absolutely beautiful....
... Beith was the occasional residence of St Inan, a confessor of some celebrity, whose principal place of abode was at Irvine. He flourished about 839. On the Cuff Hill there is a cleft in the rock, which is still called St Inan's Chair; and, at a short distance from it, a well of excellent water, called St Inan's Well. From the Callendar of Scots Saints, we find that the festival of this saint was celebrated on the 18th of August; and to this day there is a fair at Beith, held on the corresponding day, old style. Tradition still bears that this fair used to be held on the Cuff Hill. It was removed to Beith after the town had increased in population, and become a more suitable place for a market. It is one of the principal fairs in the county. The fair is vulgarly pronounced Tenant's Day; but this is evidently a corruption arising from the final letter of Saint, being sounded with the name Inan. Similar corruptions occur in Tantony, which is a corruption of St Antony; and Taudrey, which is a corruption of St Audrey. [...]
But the Cuff Hill has antiquities much earlier than the days of St Inan. On the north declivity of the hill, there is a rocking-stone of considerable size, which can be set in motion by the slightest touch. This stone is of common trap.

Cuff Hill was hacked into for road material in the early 19th century. Burl quotes a local farmer who indignantly observed "These curious and interesting relics of antiquity, the mercenary and boorish labourers are breaking and undoing with the most unfeeling apathy."
