To the west of the road is St James's Park. To the east, between Horse Guards Road and Whitehall, are various government buildings, including the five interconnected Admiralty buildings. The Old Admiralty (Ripley) Building, the oldest of the Government offices, was completed in 1726. The Horse Guards building, completed in 1759, originally housed barracks and government offices. Adjacent to the Horse Guards building is a large courtyard, Horse Guards Parade,[3] where the annual Trooping the Colour ceremony is held in the presence of the reigning monarch.
