The plans for King Charles III's coronation have been years in the making - under the codename Operation Golden Orb.
The ancient religious tradition is a service in which every monarch must swear an oath before the nation to serve them as King or Queen.
Following the Queen's death last week, her first son Charles, 73, instantly succeeded to the throne but his coronation may not be for months to come, with no plans revealed as yet.
The deeply religious Anglican service will be full of pomp and ceremony as per tradition but is expected to be more inclusive of multi-faith Britain than past coronations.
It will take place at Westminster Abbey and see Camilla crowned as Queen Consort by his side.
When the King's mother Queen Elizabeth II was crowned in February 1952, 16 months passed before her coronation in June 1953.
This means Charles is likely to be officially crowned long before his coronation.
The Stone of Destiny will be moved from Edinburgh Castle to London for the coronation of the new King, it was confirmed this week.
The stone is an ancient symbol of Scotland's monarchy, used for centuries in the inauguration of its kings and a sacred artefact.
When Elizabeth II was crowned, her throne sat above the stone but the historic object was returned to Scotland more than quarter of a century ago.
The royal families of Scotland and England are related, with their family trees intertwined more than seven centuries ago.
Elizabeth II is related to Robert the Bruce, Scotland's 14th century King - a question which tech giant Google says has been trending on its search engine.
The family tree connecting the two monarchs over 700 years runs through the late Queen's direct ancestry from James I, who united the thrones of England and Scotland.
The start of King Charles reign brings with it a new era, which many believe will be dubbed the Carolean era - derived from Carolus which is Latin for 'Charles'.
Prime Minister Liz Truss told the Commons that British people, the Commonwealth and all MPs must support Charles as he takes the country forward to a "new era of hope and progress, our new Carolean age".
New coins and notes will need to be designed and minted or printed but are not likely to appear in general circulation for some time.
The Queen's coins did not appear until 1953 - the year after her accession.
Existing coins are expected to stay in use until they are gradually replaced.
Some coins featuring King George VI stayed in circulation until the 1970s.
The Royal Mint Advisory Committee needs to send recommendations for new coins to the Chancellor and obtain royal approval.
Designs are then chosen and the final choices approved by the Chancellor and then the King.
Coins featuring Charles will show him facing to the left whereas Elizabeth II faced to the right.
It is a tradition from the 17th century to alternate the way successive monarchs are facing.
