A mounted guard on a dark horse stands beneath a stone archway at Horse Guards, London, United Kingdom. The guard wears a red ceremonial tunic, white gauntlets, black boots, and a gold plumed helmet, holding a sword. The horse, dark in color with a white blaze and white lower leg markings, is equipped with a bridle and a saddle covered by white sheepskin. To the right of the archway, on a cobblestone surface, a group of civilians observes. A female individual in blue jeans holds a small child wearing a yellow jacket. A male individual stands behind them, and other people with a stroller are partially visible further right. A decorative black metal street lamp and railings are present to the right of the archway, which is part of a larger stone building under an overcast sky. A security camera is visible mounted within the archway.
