The Cenotaph is a war memorial on Whitehall in London, England. Designed by Sir Edwin Lutyens, it was unveiled in 1920 as the United Kingdom's national memorial to the dead of Britain and the British Empire of the First World War, was rededicated in 1946 to include those of the Second World War, and has since come to represent the Commonwealth casualties from those and subsequent conflicts. The word cenotaph is derived from Greek, meaning 'empty tomb'. Most of the dead were buried close to where they fell; thus, the Cenotaph symbolises their absence and is a focal point for public mourning. The original temporary Cenotaph was erected in 1919 for a parade celebrating the end of the First World War, at which more than 15,000 servicemen, including French and American soldiers, saluted the monument. More than a million people visited the site within a week of the parade.
Calls for the Cenotaph to be rebuilt in permanent form began almost immediately. After some debate, the government agreed and construction work began in May 1920. Lutyens added entasis (curvature) but otherwise made minimal design alterations. The Cenotaph is built from Portland stone. It takes the form of a tomb chest atop a rectangular pylon, which diminishes as it rises. Three flags hang from each of the long sides. The memorial is austere, containing almost no decoration. The permanent Cenotaph was unveiled by King George V on 11 November 1920 in a ceremony combined with the repatriation of the Unknown Warrior, an unidentified British serviceman to be interred in Westminster Abbey. After the unveiling, millions more people visited the Cenotaph and the Unknown Warrior. The memorial met with public acclaim and has largely been praised by academics, though some Christian organisations disapproved of its lack of overt religious symbolism.
