As of early 2026, King Charles III and Queen Camilla are the primary residents of Windsor Castle, though it serves as their "weekend residence" rather than their full-time home (which remains Clarence House or Buckingham Palace). Following the tradition of the late Queen Elizabeth II, the Royal Standard flag is flown from the Round Tower when the King is in residence, and the Union Jack is flown when he is away. Beyond the Royal Family, the castle is a living community; it houses the Constable and Governor of Windsor Castle, the Military Knights of Windsor, and various staff members who maintain the 13-acre estate. The Prince and Princess of Wales (William and Catherine) also live on the broader Windsor Home Park estate at Adelaide Cottage, which allows them to be close to the King while maintaining a more private family life for their children. While the State Apartments are open to the public as a museum, the "Upper Ward" remains a strictly private residence for the Sovereign, guarded by the iconic soldiers of the Household Division in their red tunics and bearskin hats.
