Initially the Cenotaph was erected as a temporary structure of wood and plaster as part of the celebrations for the end of World War 1 in 1919. Shortly afterwards the government approached Edwin Lutyens to design a permanent memorial to the service-people of the war and the current monument made from Portland stone is the result.
It was unveiled on 11th November 1920 the second anniversary of the armistice.
