Prince Harry led the country in remembering the fallen, laying a wreath at the National Memorial Arboretum.
Harry attended a Remembrance Service at the Armed Forces Memorial alongside veterans and representatives of the Army, Royal Navy, and RAF.
After paying his respects, he read aloud a poem, The Soldier, by war poet Rupert Brooke.
In Edinburgh, a cannon was fired at the castle to signal the start of the two-minute silence and commemorations took place at the Princes Street Garden of Remembrance and at Waverley Station.
Veterans’ charity Erskine marked Armistice Day with a service at its Glasgow, Edinburgh and Bishopton care homes.
At the Bishopton home in Renfrewshire, veterans, staff and visitors gathered around the Memorial Stone to pay tribute.
Lieutenant Colonel Steve Conway, Erskine’s CEO, read Laurence Binyon’s lines from For The Fallen before bugler Jennifer Rollo marked the start and close of the two-minute silence.
Lt Col Conway said: “Armistice Day and Remembrance Sunday are two very significant dates for our veterans, as we remember those who made the ultimate sacrifice in conflicts from the First World War to the present day.
“Some of our residents saw active service in the Second World War and others, as well as some staff members, served in subsequent conflicts which may have been more limited geographically but which still had a devastating effect on individuals and families.
“At this time of year we remember all those who gave their lives so that we might live in freedom, and we honour their memory by caring for those that did return.”
In Glasgow, a service was held at the cenotaph in George Square.
