The ranger for the 15,000-acre Great Park of Windsor Castle is none other than the Duke of Edinburgh.

The ranger for the 15,000-acre Great Park of Windsor Castle is none other than Prince Philip, the Duke of Edinburgh. With more than 50 years of service, Prince Philip is the longest-serving ranger in the castle's history. The grounds have a pageantry of their own. The greatest event in the British polo calendar, Cartier International Day, takes place on the stunning grounds. This year the star attraction is Prince Harry, who leads the royal team. But nothing is grander than a royal wedding, as Prince Charles and Camilla Parker Bowles celebrate their nuptials at Windsor Castle. With 35,000 daffodils, 19,500 canapés, over 2,000 well-wishers and 800 guests for the prayer and dedication at St. George's Chapel, the staff is hard at work. As far as Prince Philip is concerned, though, his main duty as ranger is to be a custodian for the future. The real strength of Windsor Castle will always lie in its people, who enthusiastically share their love and passion for the castle.
