As of 2026, the individual formerly known as Prince Charles is King Charles III, and he does indeed own and have access to several castles and estates in Scotland. Most significantly, he inherited Balmoral Castle in Aberdeenshire as a private property following the death of Queen Elizabeth II; unlike official royal residences, Balmoral is owned personally by the monarch. He also owns Birkhall, a grand house on the Balmoral estate that was a favorite of the Queen Mother. Additionally, through the Prince's Foundation, he restored and manages The Castle of Mey in Caithness, which he inherited from his grandmother. While the Palace of Holyroodhouse in Edinburgh is the official residence of the British monarch in Scotland, it is part of the Crown Estate rather than the King's personal property. His deep connection to Scotland is further evidenced by his frequent stays at these residences, where he often engages in local traditions and manages the extensive Highland estates.
