Crowning
The Archbishop will bring the St Edward's Crown from the altar and place it on the King's head, who will be seated in the Coronation Chair, holding the two sceptres.
The crown is only ever used at the moment of crowning, and was created for the coronation of Charles II in 1661, making it one of the oldest symbols of the British monarchy.
The St Edward's Crown, the centrepiece of the Crown Jewels
It is a replacement of an earlier medieval crown that was melted down by parliamentarians in 1649 after the execution of King Charles I, during the English Civil War.
The crown features a solid gold frame, weighs 2.23kg and is adorned with 444 precious stones. It features four crosses pattee and four fleurs-de-lis, and the arches are surmounted by a cross.
Gun Salutes
From military bases in all corners of the country - including at firing stations in Edinburgh, Cardiff and Belfast, and on His Majesty’s ships at sea - gun salutes will sound out to herald the moment when the King is crowned.
Featuring more than 400 personnel across 13 locations and deployed Royal Navy ships, 21 rounds will fire to mark the Coronation.
Meanwhile, a 62 round salute and a six-gun salvo will fire at both the Tower of London and Horse Guards Parade.
Enthronement
After the crowning, the King will be escorted from the Coronation Chair and to the throne, symbolically taking possession of his kingdom.
