On May 16, the King, 76, and the Prince of Wales, 42, stepped out together to attend the Service for the Order of the Bath at Westminster Abbey in London. The commemoration was extra special as it is the Order's 300th anniversary year and the Service for the Order of the Bath happens only every four years. The latest iteration is King Charles' first Service as sovereign and one with a special spotlight for Prince William. The heir to the throne will be installed as Great Master of the Order during the ceremony, which includes taking an oath and installing five Knights. The Most Honourable Order of the Bath was created through the Letters Patent of George I in May 1725 and recognizes the work of military officials and senior civil servants. The Order revives an older tradition tracing back to medieval times. According to that lore, soldiers would prepare to receive their knighthood with a ritualistic bath symbolic of spiritual purification and partake in a vigil the night before receiving their honor. The Order of the Bath features three classes of members: Knight Grand Cross or Dame Grand Cross, Knight Commander or Dame Commander and Companion. Women were admitted to the Order of the Bath in 1971 with Princess Alice, Duchess of Gloucester (and the mother of modern working royal Prince Richard) named as the first Dame Grand Cross.
