Our beautiful country house tells of the multi-generational love story of the Armstrong-Jones family. Each room individually designed around the person they represent with months of research going into each room. The many chapters of incredible people who loved Plas Dinas Country House, just like we do.
Sir Robert Armstrong-Jones, CBE JP DL FRCS FRCP FSA (born Robert Jones; 2 December 1857 – 30 January 1943) was a Welsh physician and psychiatrist. He was a leading psychologist in psychosomatic behaviour and supported the army in World War I.
He was educated at Porthmadog Grammar School and Grove Park School, Wrexham, going on to study medicine at University of Wales, Bangor, and St. Bartholomew's Hospital. Sir Robert then lectured at St Bartholomew's Hospital, and became consulting physician in mental diseases to the military forces at London and Aldershot.
In 1913, he assumed the additional surname of Armstrong, which had been the maiden name of his wife's grandmother, Jane née Armstrong, because he wanted to distinguish himself from another prominent Robert Jones of the time.
During World War I, he was designated a Lieutenant-Colonel in the Royal Army Medical Corps; he was knighted in the 1917 New Year Honours, and after the war he was appointed a Commander of the Order of the British Empire (CBE) in recognition of his war service. He was appointed High Sheriff of Caernarvonshire for 1929. He was a Fellow of both the Royal College of Physicians and the Royal College of Surgeons.
Sir Robert married Margaret Roberts in 1893 and went on to welcome Ronald (Lord Snowdon's Father), Elaine and Gwendolen who you will all know as Lady Buckley.
He sadly passed in 1943 and sadly Margaret only survived a further 4 months after his passing.
Back in August 2024 we released the Sir Robert room, a room dedicated to his passion for psychology. A love story that is now back together here at Plas Dinas.
