Upon his accession to the throne, King Charles inherited a vast property portfolio from his mother the late Queen - and now has properties dotted across the country.
Some he has been making use of such as Buckingham Palace, Windsor Castle and Sandringham.
However, some he nor the late Queen have never even lived in - including one on the Windsor estate, which could have been a potential home for the Prince and Princess of Wales before they decided to move to Adelaide Cottage.
