On the summit of Mount Corrin there is an impressive stone cairn (Péicín na gCloch) probaby built over an ancient burial on what would have been an important site in ancient times. Also, in a sheltered dip on the eastern slope to the north east of the cairn are the low stone walls and rubble remains of three Booley Huts used for pasturing cattle in the summer months.
