April 2019 — Seen from St James’s Park, the Horse Guards building stands as one of London’s most recognizable 18th-century landmarks. Completed in 1755 and designed by William Kent, it served as the headquarters for the British Army’s Commander-in-Chief and remains the official entrance to St James’s and Buckingham Palace. The twin domes crown the clock tower that marks the central archway, through which The Household Cavalry still passes during ceremonial events. Behind it, the turrets of the Old War Office and Whitehall’s ministries rise, linking centuries of British military and government history into one dense architectural corridor.
