The Queen&#39;s Bedroom, looking north west. This room was used by Queen Mary II as her State Bedroom. The state bed in the room today is traditionally regarded as the bed made for King James II and Mary of Modena. It is sometimes known as the &#39;warming pan bed&#39; and is associated with the birth of Prince James Francis Edward Stuart (the &#39;Old Pretender&#39;) at St James&#39;s Palace in 1688.
