 The erection by of a commemorative bronze bust of Kettle in Dublin, commissioned from the sculptor Albert Power and finished in 1921, was beset for almost twenty years by controversy and bureaucratic obstruction due to the antipathy of the State authorities post-Independence towards Irishmen who had fought in World War 1.It was finally raised in 1937, without an unveiling ceremony, in St. Stephen's Green.A stone tablet commemorates him in the Island of Ireland Peace Park, at Messines, Belgium and he is listed on the bronze plaque in the Four Courts Dublin which commemorates the 26 Irish barristers killed in the Great War.
