King Charles and Queen Camilla will be formally presented with the Scottish crown jewels today in a special ceremony to honour the new monarch.
The King will receive a crown, a sceptre and a sword made of gold, silver and gems - known collectively as the Honours of Scotland - during a service of thanksgiving and dedication at St Giles' Cathedral, Edinburgh.
Later in the day, spectators will be treated to a Red Arrows display over the Royal Mile past the Palace of Holyroodhouse and Edinburgh Castle.
The RAF in Scotland tweeted: "Members of the Royal Air Force will join colleagues from the Royal Navy and British Army to celebrate the King’s coronation.
"The King's Colour Squadron and Royal Air Force Central Scotland will escort the Honours of Scotland from Edinburgh Castle to St Giles' Cathedral where they will be presented.
"RAF Music trumpeters will provide support during the service of thanksgiving. The finale will be a flypast from the Red Arrows over Holyrood Palace when the King and Queen have returned there."
It added: "A lot of hard work by all involved!"
The Red Arrows display - which is subject to weather - will take place at 3.45pm.
Meanwhile, ahead of the ceremony, more than 700 members of the Armed Forces are set to take part in a procession along the Royal Mile.
The procession will be led by Shetland pony Corporal Cruachan IV, the mascot of The Royal Regiment of Scotland, alongside personnel from The Royal Scots Dragoon Guards and the Army Cadet Force.
The ceremony itself will feature personnel from across the Household Cavalry Mounted Regiment, The Royal Regiment of Scotland (SCOTS), and Scottish and North Irish Yeomanry.
Musicians from across the Armed Forces will also take part in the event and will include personnel from Royal Marines Band Scotland, Band SCOTS and Pipes and Drums from the Army and RAF.
A tri-service Guard of Honour will receive Their Majesties' and The Duke and Duchess of Rothesay at the Palace of Holyroodhouse before the service.
Scottish Secretary Alister Jack said ahead of the service: "Scotland's Armed Forces will play a key role in the service to present The King and Queen with the Honours of Scotland. It is right and fitting that they do.
"Having been such a crucial part of Queen Elizabeth's funeral, they will now be central to this important moment for King Charles. I very much look forward to seeing our military personnel at their very best."
Service personnel last took part in the presentation of the Honours of Scotland in 1953, when they were presented to Her Majesty Queen Elizabeth II.
The presentation of the Honours of Scotland marks the dedication of the King and Queen in Scotland and has origins dating back to the 1800s, when they were presented to King George IV.
Defence Secretary Ben Wallace said: "Today is a historic day for Scotland and a proud day for the hundreds of service personnel involved who will be at the forefront of the occasion, showcasing their world-class drill and ceremonial duties once again.
"The Armed Forces have a strong and deep-rooted connection to Scotland, so it is only fitting that they lead the formal proceedings of the day in such a spectacular way."
