John O’Donovan stayed in Banagher from 10-21 January 1834 where he was accompanied by Thomas O’Connor. As mentioned in a previous blog he used his time there to look at two historic sites in particular, in addition to his normal work. He first concentrated on Clonmacnoise, writing his first substantial and detailed letters on 15 January 1838. This followed on from his request that documents be sent from Dublin ahead of his arrival.
