Joseph P. Fenwick, in his essay which is contained in the book “Roscommon History and Society”, describes Rathcroghan as “A once thriving royal site and pre-Christian cult centre as evidenced by well preserved monuments” and goes on to say that it “served as a nexus of political power and religious potency.” It was thought to be the place where the “world king would come to intercede with the gods of the otherworld on behalf of his people.”
