Passage: The sovereign's official residence in London is Buckingham Palace. It is the site of most state banquets, investitures, royal christenings and other ceremonies. Another official residence is Windsor Castle, the largest occupied castle in the world, which is used principally at weekends, Easter and during Royal Ascot, an annual race meeting that is part of the social calendar. The sovereign's official residence in Scotland is the Palace of Holyroodhouse in Edinburgh. The monarch stays at Holyrood for at least one week each year, and when visiting Scotland on state occasions.Historically, the Palace of Westminster and the Tower of London were the main residences of the English Sovereign until Henry VIII acquired the Palace of Whitehall. Whitehall was destroyed by fire in 1698, leading to a shift to St James's Palace. Although replaced as the monarch's primary London residence by Buckingham Palace in 1837, St James's is still the senior palace and remains the ceremonial Royal residence. For example, foreign ambassadors are accredited to the Court of St James's, and the Palace is the site of the meeting of the Accession Council. It is also used by other members of the Royal Family.Other residences include Clarence House and Kensington Palace. The palaces belong to the Crown; they are held in trust for future rulers, and cannot be sold by the monarch. Sandringham House in Norfolk and Balmoral Castle in Aberdeenshire are privately owned by the Queen.
