The parade ground is open on the west side, where it faces Horse Guards Road and St. James's Park. It is flanked on the north by the Old Admiralty and the Admiralty Citadel, on the east by William Kent's Horse Guards – formerly the headquarters of the British Army – and on the south by the Foreign & Commonwealth Office and the rear garden wall of 10 Downing Street, the official residence of the British Prime Minister. Access to this side of Horse Guards Parade is now restricted for security reasons.
