Battle of Britain Memorial

The Battle of Britain Monument in London is a sculpture on the Victoria Embankment overlooking the River Thames in central London, England which pays tribute to those who took part in the Battle of Britain during World War II. It was unveiled on 18 September 2005, the 65th anniversary of the Battle, by His Royal Highnesses the Prince of Wales and Her Royal Highness the Duchess of Cornwall in the presence of many of the surviving airmen known collectively as "The Few", following the Royal Air Force Service of Thanksgiving and Rededication on Battle of Britain Sunday. This service is an annual event, taking place annually since 1943; the first service took place in St Paul's Cathedral and since has taken place in Westminster Abbey.
