When Queen Elizabeth II died on Sept. 8, 2022 at age 96, she set off a chain of events, called Operation London Bridge, that have been in the planning stages for decades.
One part of that complex plan is the burial of the UK's longest-reigning monarch.
Queen Elizabeth will be laid to rest in the King George VI memorial chapel in Windsor alongside the remains of her parents and her sister Princess Margaret, where she'll be joined by her husband of 73 years.
When Prince Philip he died in April 2021 at the age of 99, he was interred in the Royal Vault beneath St George's Chapel at Windsor Castle.
But this isn't his final resting place—his coffin will be moved to the burial vault in Windsor now that the queen has died.

A national public holiday has been declared in the United Kingdom for Sept. 19 in honor of the queen.
In keeping with royal tradition, the queen will be buried in a lead-lined coffin.
On the day of the funeral, the service will begin at 5:45 a.m. ET, when King Charles, Prince William, Prince Harry and other royals will escort the queen's casket to Westminster Abbey.
The state funeral service (the first in the UK since Winston Churchill died in 1965) will begin at 6 a.m. ET and run for just an hour
The queen's committal service is scheduled for Monday, Sept. 19, at St George's Chapel and will be attended by more than 800 people. It's unclear at this time when they'll move to Windsor Castle from Westminster Abbey.
Queen Elizabeth will be buried in a private ceremony at 2:30 p.m. ET.
Although unlikely as this point, some reports have also suggested that rather than being buried in the memorial chapel, the queen and Philip's ultimate resting place will be on the grounds of Frogmore House on the Windsor Estate.
It's possible that a special mausoleum will be built at a later date for the queen and Philip like the one in which Queen Victoria and Prince Albert are interred, and whose tomb is marked by the royal couple's marble effigies depicted lying side-by-side.
