The poem that inspired the creation of 888,246 poppies to envelop the Tower of London was written by a First World War soldier whose name no one knows.
The display takes its name from the poem's opening line, "The Blood Swept Lands and Seas of Red."
Here Yeoman Warder Jim Duncan reads that ode:
Across Britain a two-minute silence took place to mark Armistice Day a century after the start of the First World War.
People stood wherever they were at 11am to remember the fallen especially during the Great War.
ITV News correspondent Dan Rivers reports on acts of remembrance held across the country:
In France and Belgium events were held to honour the soldiers who died during the First World War.
A new memorial to the dead was inaugurated on the battlefield in Arras honouring the fallen from every nation who died in northern France
ITV News' Europe Editor James Mates was at the opening of the 'Ring of Memory'.
A final ceramic poppy was planted at the Tower of London today to mark Armistice Day.
In total 888,246 poppies were installed to represent every soldier who died for Britain and the Commonwealth in the First World War.
ITV News' Senior Correspondent Emma Murphy reports on a poignant act of remembrance.
People all around the world stood in silence for two minutes at the 11th hour, on the 11th day, of the 11th month to mark Armistice Day.
In Ypres, in Belgium, the last post was played at the Menin Gate. The two minute's silence was brought to an end by Scottish piper, Major John Fraser.
Red poppies were released from the roof, floating down on to veterans and families under the gate.
General Lord Dannatt, the Constable of the Tower of London has spoken of how moving the installation Blood Swept Lands and Seas of Red has been and the respect the public have shown for it.
Speaking to ITV News Lord Dannatt said:
I think it is that specific number of 888,246 that actually has brought the commemorative installation alive to people. Because that number represents a mass army, but they're individuals and individual whose life was lost, a family shattered.
I think the five million people who have come to see this understand what the effect would be of losing a family member.
The silence today is typical of what's been happening all the time for the last few weeks. Every evening at dusk we've read the names of 200 of the fallen and you could a pin drop on any of those occasions.
And even during the afternoons and the mornings when there have been tens of thousands of people coming it has been very hushed, it's been very reverent, it's been very reflective, it's been very emotion. It's been probably very British - in a rather un-British way.
ITV Central viewers have been sending in pictures of how they have been commemorating Armistice Day.
People across the Midlands have paid tribute to the servicemen who have died in conflict since the start of the First World War 100-years-ago.
Children at a primary school in Stourbridge have made a giant, human poppy to commemorate Remembrance Day.
The Tower of London's Blood Swept Lands and Seas of Red installation has been recreated in Lego for Armistice Day.

4,000 poppy petals were dropped in memory of the country's war heroes at West Orchards Shopping Centre in Coventry.
