The late Prince Philip was very fond of the humble property, and it's reportedly where he spent most of his time after retiring from public duties in August 2017, residing separately from Her Majesty.
The five-bedroom farmhouse is set within a picturesque corner of the stunning 600-acre estate, but it is rather low-key inside, far from the gilded grandeur of royal residences such as Buckingham Palace.
