Horse Guards Building Behind St James’s Park Lake

The Horse Guards building, completed in 1755 and designed by William Kent, is a prominent 18th-century landmark in London. Situated behind St. James's Park Lake, it historically served as the headquarters for the British Army's Commander-in-Chief. The building's central archway, topped by twin domes on its clock tower, is still used by The Household Cavalry for ceremonial processions. Adjacent structures, including the Old War Office and Whitehall ministries, underscore its long-standing connection to British military and governmental history.
