According to Hello, it is a long-standing tradition for members of the British royal family to breathe their last breaths at home, surrounded by their loving families. The Queen once called her Scottish summer home "my beloved paradise in the highlands." [The Queen's two eldest sons, Prince Charles and Princess Anne, were already in Scotland today when the Queen's health deteriorated. According to the magazine, "Prince Charles and Princess Anne rushed to her bedside Thursday morning after the Queen was placed under medical supervision."

Her two younger children, Prince Andrew and Prince Edward, arrived shortly after, along with grandson Prince William. Prince Harry is said to have arrived separately in Balmoral. Although currently living in the U.S., both Harry and his wife, Meghan Markle, were already in the U.K. for a previously scheduled charity event. Meghan will remain in Windsor and has cancelled her attendance at the Wellchild Awards in London tonight. William's wife, Kate Middleton, also remained in Windsor to oversee her three children's first day of school at Lambrook today.

Her Majesty spent August through October each year at her Aberdeenshire mansion and "frequently invited members of her family," Hello! reported. Balmoral has belonged to the British royal family since 1852 and is located in the Scottish countryside.

Earlier this week, we last saw photos of the Queen appointing new Prime Minister Liz Truss at Balmoral for the first time. On Thursday afternoon, Buckingham Palace issued a statement. 'Following further assessments this morning, the Queen's doctors have expressed concern for Her Majesty's health and have recommended that she be placed under medical supervision. The Queen remains in Balmoral in comfort."
