The image shows five large, green, wooden cannons lined up in a row along the wall of a castle. The cannons have spokes like a wheel and have black metal bands wrapped around them. The cannons are aligned from left to right with the wheels slightly overlapping. Behind the cannons, a stone wall has a window and a black door. In the right side of the image, a person wearing a red uniform and a black fur hat stands facing the cannons. The person is a member of the British Royal Guard. The ground in front of the cannons is made of brown bricks and has a black metal railing.
