Windsor Castle, the world's oldest and largest inhabited castle, is owned by the British monarch in right of the Crown. It serves as both a private weekend retreat and an official royal residence.
King Charles III uses the castle for state occasions, official entertaining, and as a working palace. The late Queen Elizabeth II spent much of her time there, especially in her later years. The estate is managed by the Royal Household and maintained by the Crown Estate.
Located in Berkshire, England, Windsor Castle remains a potent symbol of the monarchy's continuity and a major tourist attraction.
