The office of Ranger of Windsor Great Park was established to oversee the protection and maintenance of the Great Park at Windsor in the English county of Berkshire.
One of the most famous rangers was Sarah, Duchess of Marlborough, who was given the position by her friend, Queen Anne, in 1702.
Cumberland Lodge within the Park ceased to be the official residence for the rangers in 1917.
The former ranger (Prince Philip) had tried to make it more open to the public, more sustainable, and to keep it going for future generations.
In an interview for the BBC TV programme "The Queen's Castle" he gave a tour of the Park, explained his thoughts and actions in making decisions to open the Farm Shop, cut down trees, move various facilities, and to open up the park to deer as well as people.
