Ringforts such as Caherconnell are thought to have been inhabited from 400-1200A.D. However a description of the site at Caherconnell, in the early 20th century by local historian the late Dr. McNamara of Corofin Co. Clare suggests that the entrance to the fort may have been re-built in the 15th or 16th century. This suggests that this fort may have been inhabited up to the late medieval period.
