sentences:  Surviving documents such as a "Confirmatio" of 1314/1315 which recognised the existence, rights and liberties of ""collegio de Ruthin fundato per Reginald de Grey"" indicate the existence of the School but nothing more is known of the size of the establishment.Following Owain Glyndŵr's attack on Ruthin in September 1400, it appears that the collegiate church, and presumably also the school, continued to function unscathed until the dissolution of the former in 1535.Evidence for the school's continuation over the following decades is sketchy, but it is known that in 1561 the tithes of the sinecure of Llanelidan were applied to the use of the school, which suggests that pupils at that time would have been from local homes.
