Known simply as 'the Chair', this peculiar arrangement of rocks near Clogher forms what appears to be a deliberate seat-like structure. Recorded as Site No. 1864 in the 1983 Donegal Survey, it consists of several stones positioned in such a way that they create a natural throne, though whether by ancient design or geological chance remains a mystery.

The site has puzzled archaeologists enough that it defies easy categorisation; both the 1987 Sites and Monuments Record and the 1994 Record of Monuments and Places classify it rather vaguely as 'Miscellaneous'. This classification speaks to the difficulty in determining its original purpose, if indeed it had one beyond its current role as a local curiosity. Some suggest it could be a natural formation that locals have long used as a resting spot, whilst others wonder if it might have held ritual significance in the distant past.

Today, the Chair stands as one of those wonderfully ambiguous features of the Irish landscape that refuses to give up its secrets. Its stone construction has weathered countless seasons, and whether it was crafted by human hands or shaped by nature, it continues to invite visitors to take a seat and ponder the mysteries of Donegal's ancient past. The lack of definitive archaeological evidence only adds to its charm, making it a perfect example of Ireland's many enigmatic monuments that blur the line between natural wonder and human creation.
