The Tower of London will mark the 100-year anniversary of the First World War with an installation created by ceramic artist Paul Cummins. The Tower's famous dry moat is being slowly filled with red poppies — each representing a British or Colonial fatality during the war.

888,246 Ceramic Poppies Will Fill The Moat At The Tower Of London

Volunteers have already begun planting the ceramic flowers for the installation, which is entitled Blood Swept Lands and Seas of Red. The official unveiling will take place on August 5, exactly one century since the first full day of Britain's involvement in the war. The final poppy will be symbolically planted on November 11—the UK's day of remembrance for commemorating the end of the conflict.

The poppies will be sold, with proceeds going to charities for veterans.
