This is a wide view inside St. George's Chapel at Windsor Castle as members of the royal family took their seats for the funeral of Prince Philip, Duke of Edinburgh on April 17, 2021.

However, it will not be his final resting place. Following the death of his wife, Queen Elizabeth II, the Duke of Edinburgh's casket will be moved to be with hers inside the King George IV Memorial Chapel, which is also located inside the church. That small chapel is where the queen's parents, King George VI and Queen Elizabeth the Queen Mother, are buried and where the ashes of her sister, Princess Margaret, are interred.
