Remembrance day has been observed on the 11th hour of the 11th day of the 11th month since King George V issued a proclamation calling for two minutes silence - "All locomotion should cease, so that, in perfect stillness, the thoughts of everyone may be concentrated on reverent remembrance of the glorious dead."

15. The major art installation Blood Swept Lands and Seas of Red at the Tower of London, marking one hundred years since the first full day of Britain's involvement in the First World War. Created by ceramic artist Paul Cummins, with setting by stage designer Tom Piper, 888,246 ceramic poppies will progressively fill the Tower's famous moat over the summer. Each poppy represents a British military fatality during the war. The poppies will encircle the iconic landmark, creating not only a spectacular display visible from all around the Tower but also a location for personal reflection.
