Queen Elizabeth II and Prince Philip have been together for years and they will most likely be buried in the same location.

But on the online forum site Quora, some royal fans are wondering where Her Majesty and the Duke of Edinburgh would be laid to rest. There are also some speculations suggesting that the royal couple could be buried in two different locations.

Chris Smith, a teacher, explained the logic behind the royal couple’s different burial sites. He said that when the Queen commissioned George VI Chapel at St. George’s Chapel in Windsor Castle where Prince Harry and Meghan Markle tied the knot, the vault was built to be large enough for six coffins. The ones who could be interred there are George VI, the Queen Mother, the Queen, Prince Philip, Prince Charles and Camilla Parker Bowles.

But when Princess Margaret died in 2002, she wanted to be buried with her parents. Since only six coffins may fit in the chapel, Princess Margaret was cremated, and her ashes were placed in the chapel.

Gill Bullen, an avid fan of English history, said that as far as she is aware, the Queen and Prince Philip would be buried together in Windsor.

“I first heard of this when I was still in school and singing in a choir in the local cathedral. The Cathedral was having some building work done and the architect was to be a Mr. Pace who had recently been responsible for the design of the tombs at Windsor for both the Queen and the Duke of Edinburgh,” she said.

Tony Bartlett said that the Queen would like to be buried at Frogmore. But since has become the longest-serving monarch, she would most likely be buried at Westminster Abbey. The Duke of Edinburgh, on the other hand, is not a monarch or a King so he cannot be buried at Westminster Abbey.

Prince Philip and the Queen have been married for over decades. The former is 97 years old while the latter just turned 93 years old last month.
