On the King's death, Sandringham passed to his daughter Elizabeth II. The Queen spends about two months each winter on the Sandringham Estate, including the anniversary of her father's death and of her own accession in early February. In 1957 she broadcast her first televised Christmas message from Sandringham. In the 1960s, plans were drawn up to demolish the house and replace it with a modern building, but these were not carried out. In 1977, for her Silver Jubilee, the Queen opened the house and grounds to the public for the first time. Unlike the royal palaces, such as Buckingham Palace and Windsor Castle, Sandringham and Balmoral Castle are the Queen's private homes.
