A sea of poppies is gradually engulfing the moat of the Tower of London as part of a huge installation to mark the centenary of the outbreak of World War 1. Blood Swept Lands and Seas of Red, which will eventually consist of 888,246 ceramic poppies, is the work of artist Paul Cummins. It was publicly unveiled on August 5 and will continue to be added to until Armistice Day on November 11. The poppies are available to buy for £25 each with the proceeds being shared equally amongst selected Service charities. Each poppy, the traditional symbol of remembrance in Britain, represents a each British and Colonial fatality during the war. You can buy a poppy here.
