Dignitaries including Baroness Thatcher, the prime minister in 1982, joined Falklands War veterans at a service in Berkshire to mark 25 years since the end of the conflict
The Falkland Islands Memorial Chapel is a national memorial building designed to commemorate the lives of the 255 UK servicemen and three islanders who died in the conflict.
Former college student Rear Admiral Jeremy Sanders CB OBE, who served in the conflict, read the traditional act of remembrance.
Among the congregation was the widow of Lt Col "H" Jones, one of the best known heroes of the conflict, who was posthumously awarded the Victoria Cross.
This week Baroness Thatcher addressed Falkland Islanders in a radio message saying "we should still rejoice" at the victory in 1982
Mr Blair has said going to war over the Falklands took "political courage" and was "the right thing to do".
Following the service the Queen laid the 255th stone on a memorial cairn. Each stone was brought from the Falklands - one for every member of the UK armed forces who died.
