The coffin of the late Queen Elizabeth II arrived in Edinburgh on Sunday after a six hour journey from Balmoral Castle, the first part of a long-standing plan that was triggered when she died.
The queen left the Scottish countryside for the final time on Sunday and thousands of people turned up to watch her motorcade go by.
Holyroodhouse, the monarchy's official Scottish residence and its smallest palace, will be used as a resting place for the coffin for one day.
On Tuesday, the queen's coffin will be flown from Edinburgh Airport to a military base outside London, where it will be taken to Buckingham Palace.
Members of the public will be able to pay their respects to the coffin over the course of four days as it lies in state in the Palace of Westminster.
Hundreds of foreign officials and royals are expected to attend the state funeral that will be held the following Monday at nearby Westminster Abbey.
The queen will be buried in St. George's Chapel next to her father, King George VI, and her sister, Princess Margaret.
The United Kingdom has a new monarch for the first time in seven decades since Queen Elizabeth died. A series of contingency plans for the queen's death were introduced in the royal household in the 1960's. A piece published in The Guardian last year sheds light on the specific plans to be put into motion if the queen were to die in Scotland, a situation that became reality last year. If the queen's casket were to be taken from Scotland to England by train, a plan known as "Operation Overstudy" would have been put in place, according to documents obtained by Politico. Since the documents were obtained, the preparations may have been changed.
After the service at St Giles' Cathedral, King Charles III will have his first audience. The leader of the Scottish National Party wants Scotland to leave the United Kingdom and become independent. The death of the queen has been linked to independence. One in three people in Scotland think it would be a good idea to abolish the monarchy when the queen dies, according to a poll. The U.K.'s decision to leave the European Union could be used to justify another independence referendum in Scotland. When asked if she would allow Scotland to leave the U.K., the new Prime Minister said she wouldn't.
