Read this: Following their wedding, the couple leased Windlesham Moor, near Windsor Castle, until 4 July 1949, when they took up residence at Clarence House in London. At various times between 1949 and 1951, the Duke of Edinburgh was stationed in the British Crown Colony of Malta as a serving Royal Navy officer. He and Elizabeth lived intermittently, for several months at a time, in the hamlet of Gwardamanga, at Villa Guardamangia, the rented home of Philip's uncle, Lord Mountbatten. The children remained in Britain.
