One of the most amazing sights: the Blood Swept Lands and Seas of Red display at the Tower of London. The display constantly changed and grew from 5 August to 11 November 2014 in remembrance of the people that lost their lives during the World War One.
First time I went to see it on 5 Augus, when they were still installing the poppies. The second time was on 13 November, when they were removing them. Most poppies were sold for charity while a small installation was kept and traveled within the UK.
