Boxes of old greeting cards and stationery items left by the previous occupant of Villa Guardamangia, a former residence of Britain's Queen Elizabeth and Prince Philip, are stacked on top of each other, in Pieta, Malta, June 23, 2020. The then-Princess Elizabeth and Prince Philip were in the first years of their marriage at the time and moved to Malta when Prince Philip was based there in command of a Royal Navy frigate. The Maltese government agency Heritage Malta acquired the Villa Guardamangia for some five million euros and hopes not just to restore the villa to the way it looked several decades ago, but also to turn it into a museum of Malta's history as a British colony until independence in 1964, and the links with the British royal family.
