Glittering ceremonial celebrations for the King’s coronation have been unveiled, detailing the procession route, the carriages and the priceless Crown Jewels chosen to play a starring role.

Charles and the Queen Consort will travel in a shorter procession route than the late Elizabeth II and break with tradition by only using the elaborate 260-year-old Gold State Coach one way – on their return.

The monarch and Camilla have personally decided to make the 1.3 mile outward journey – known as the King’s Procession – from Buckingham Palace in the more modern, comfortable Diamond Jubilee State Coach, which has shock absorbers, heating and air conditioning.

They will travel, accompanied by The Sovereign’s Escort of the Household Cavalry, down The Mall via Admiralty Arch, along the south side of Trafalgar Square, along Whitehall and Parliament Street, around the east and south sides of Parliament Square to Broad Sanctuary to arrive at the Abbey.

Bournemouth Echo:

The coronation service on May 6 will begin at 11am.

The late Queen rode both ways in the Gold State Coach for her 1953 coronation, famously describing the bumpy experience in the carriage, which is suspended on leather straps, as “horrible”.

Her outward procession was 1.6 miles long but her return procession was five miles, taking her down Piccadilly, along Oxford Street and Regent Street and Haymarket.

It took two hours to complete, featured 16,000 participants and was designed to allow her to be seen by as many people as possible.

A newly crowned Charles and Camilla will instead travel just 1.3 miles back in the Gold State Coach after the ceremony, reversing their outward journey as they wave to the crowds, with the King wearing the Imperial State Crown.

The route is understood to have been chosen for practical reasons, being a familiar tried and tested journey for many royal occasions.

A Buckingham Palace spokesperson said: “The carriages chosen reflect the smaller procession to the Abbey and the larger procession back to Buckingham Palace.

“They were the personal choice of Their Majesties.”

The Palace declined to comment on whether the decision to opt for the Diamond Jubilee State Coach at the start has anything to do with ongoing back pain the King has suffered for many decades. Camilla has also endured back problems over the years.

The priceless array of coronation regalia from the Crown Jewels which will be used during the religious service in the Abbey has also been confirmed.

It will include the Sovereign’s Orb, the Golden Spurs, bracelets known as Armills, two maces, five symbolic swords, the Sovereign’s Ring, the Sovereign’s Sceptre with Cross and the Sovereign’s Sceptre with Dove.

Camilla will be crowned, as previously announced, with the modified Queen Mary’s Crown, but she will also hold the Queen Consort’s Rod with Dove – despite the controversial rod being made from ivory.

The piece is said to symbolise equity and mercy, and the dove, with its folded wings, represents the Holy Ghost.

Camilla will also hold the Queen Consort’s Sceptre with Cross, which originally made for the coronation of Mary of Modena, Queen Consort of James II, in 1685 and is inlaid with rock crystals.

As part of the proceedings, she will receive the Queen Consort’s Ring – a ruby in a gold setting made for the Coronation of King William IV and Queen Adelaide in 1831, and used by three further Queens Consort – Queen Alexandra, Queen Mary, and the Queen Mother.
