Across from the convent school this building was occupied by British forces during the fight for independence. On the 20th June 1920, it was attacked by members of the I.R.A. and burned to the ground. During the attack one of the attacking party was badly wounded and he died of his wounds four weeks later. A plaque to his memory is mounted on the front of the building and translates as follows:
In memory of Volunteer Michael O’Kennedy, Nenagh, who was fatally wounded in an attack on this Barrack on the night of 20/6/1920 who died on 27/7/1920 aged 27 years. ‘The grace of God on him’. Erected by his comrades of the First Tipperary Brigade.
