Thousands of people have gathered at Cardiff Castle to hear Charles be proclaimed King in Wales.
More than 2,000 people have been allowed inside the grounds since the gates opened at 10am.
Hundreds more lined the streets outside the castle walls, including two protesters holding signs reading: “Not our king!”
The former Prince of Wales ascended to the throne following the death of his mother, Queen Elizabeth II, on Thursday.
He was then formally proclaimed King at a historic ceremony in St James’s Palace in London following a meeting of the Accession Council during which he swore an oath to privy counsellors.
Proclamations will take place across the UK on Sunday, including Wales, at about midday.
Prior to the Proclamation, 26 men of the 3rd Battalion the Royal Welsh – supported by the Band of the Royal Welsh – were marching from City Hall at 11.25am along the Boulevard de Nantes, North Road and Duke Street to the castle.
They were accompanied by the regimental mascot, a Welsh billy goat called Lance Corporal Shenkin IV, and Goat Major Sergeant Mark Jackson.
Inside the castle, the Wales Herald of Arms Extraordinary, Tom Lloyd, will make the Proclamation in English and the Lord-Lieutenant of South Glamorgan, Morfudd Meredith, will proclaim King Charles in Welsh.
After the readings, members of 104th Regiment of the Royal Artillery will fire a 21-gun salute before the singing of God Save The King and Hen Wlad Fy Nhadau, Wales’s national anthem.

Flags will return to half-mast at 1pm on Sunday after the Proclamation is read in Cardiff.

All other business has been suspended until after the state funeral on Monday September 19.
Welsh Secretary Robert Buckland is attending the Proclamation ceremony, along with Wales First Minister Mark Drakeford and opposition leaders.
Well-wishers in Scotland said goodbye to the Queen as her coffin left Balmoral on a six-hour journey to Edinburgh, where it will lie at St Giles’ Cathedral. In bright sunshine, the hearse carrying the late monarch passed through the gates of the royal residence which was the summer refuge for the former head of state.
