You may well have heard about the installation Bloodswept Lands and Fields of Red at the Tower of London.
The artist who has made the poppies is Paul Cummins. His previous work has been on display outside the Palace of Westminster.
Poppies are our symbol of remembrance in the UK. Every year, as the anniversary of the armistice that ended the First World War approaches, you will find people wearing paper poppies, poppy armbands, enamel poppy brooches.
This year marks the hundredth anniversary of the start of that war. All around London and the rest of the UK, and in many other countries around the world, there are exhibitions, events and religious services to commemorate the centenary.
By Armistice Day, 11th November, there will be 888,246 ceramic poppies at the Tower; one for each member of the British and Colonial forces who died in the First World War.
It is a moving sight, one that brings home the loss of the life so much more effectively than a number on a page.
It is also extremely beautiful. People turn up, stand and stare.
If one of your family died in this war, you can contact the Tower with the details and the name will be read out one evening between now and 11th November.
Tha last poppy will be placed by the Queen in November.
