Before marrying the heir to the British throne, Prince Philip was already a prince as he was born a member of the Greek royal family. Philip left Greece when he was a child because the family was forced into exile, but Vassilis Koutsavlis, president of the Tatoi Royal Estate Friends Association, said the prince still had ties with Greece. The former royal estate at Tatoi just north of Athens includes a cemetery where many of Philip's relatives, including his father and paternal grandparents, are buried.
