Turing's father's civil service commission was still active and during Turing's childhood years, his parents travelled between Hastings in the United Kingdom[25] and India, leaving their two sons to stay with a retired Army couple. At Hastings, Turing stayed at Baston Lodge, Upper Maze Hill, St Leonards-on-Sea, now marked with a blue plaque.[26] The plaque was unveiled on 23 June 2012, the centenary of Turing's birth.[27]
