The Tower of London have famously marked the centenary of the First World War with a stunning display of ceramic poppies. An estimated four million people have gone to witness the display.
It's not always easy to get a decent view or to appreciate the sheer scale of the display. However, a drone was sent out to capture the commemoration - which it has done with vivid clarity.
With thanks to the Historical Royal Palaces for the beautiful video.
