Why is Queen Elithabeth's tomb on top of Queen Mary's?

Queen Elizabeth I's tomb is located on top of Queen Mary I's in Westminster Abbey as a reflection of their intertwined histories and royal legacies. Elizabeth I, the daughter of Henry VIII and Anne Boleyn, was the successor to Mary I, who was the daughter of Henry VIII and Catherine of Aragon. The placement symbolizes the reconciliation of their reigns, as Elizabeth's Protestant rule followed Mary's Catholic reign, marking a significant shift in English history. This arrangement also highlights the significance of both queens in shaping the monarchy and the nation.
