A beam of light shines above the Houses of Parliament as the country marks the centenary of the outbreak of WWI.
"The lamps are going out all over Europe; we shall not see them lit again in our lifetime," said Foreign Secretary Sir Edward Grey 100 years ago, on the eve of the first World War. On Monday night, Britons commemorated the centenary of the Great War by plunging the UK into darkness for an hour.
The Lights Out event marks 100 years after Britain entered the war on Aug. 4 1914. The conflict claimed millions of lives, making it one of the deadliest in human history.
The Royal British Legion, a charity that supports veterans and their families, asked people to leave just one light or candle on in their houses between 10 p.m. and 11 p.m. GMT. The organization lit over one million candles across the country in remembrance of the million British servicemen and women who died in the war.
The Legion's Fundraising Director Charles Byrne told the BBC that the initiative aimed to "pass on the torch of remembrance to a younger generation" and ensure the living legacy of "those who sacrificed their today for our tomorrows."
The Duke and Duchess of Cambridge (Prince William and Kate Middleton), Prince Harry and Prime Minister David Cameron attended a twilight ceremony at St. Symphorien Military Cemetery in Belgium, while Prince Charles attended a service in Glasgow.
