Step inside Windsor Castle and you’re walking among royalty, even in death! Over 10 monarchs are buried within St George’s Chapel, including Edward IV, Henry VIII with Jane Seymour, and Queen Elizabeth II. Of all these monarchs, Charles I’s story is especially striking. Executed for treason in 1649, he was quietly laid in Henry VIII’s vault, with no fanfare or royal ceremony, probably being the only monarch in history to receive that treatment.
