Elements of the Queen's 1953 Coronation ceremony were reflected in today's celebration service at Westminster Abbey.
When kings or queens are crowned the ritual features the recognition, oath, anointing, investiture and homage.
The Dean of Westminster told the congregation:
"Sixty years ago, in this holy place, Queen Elizabeth II was anointed with holy oil, clothed with sacred garments, and, after receiving symbols of authority, crowned with the Crown of St Edward, King and Confessor, just as Her Majesty's royal predecessors from 1066.
"Here today we gather to give thanks to almighty God for the faithful ministry and dutiful service the Queen continues to offer God and the people of this nation, the overseas territories and the realms, and as head of the Commonwealth."
