The image shows a large, grey submarine on display in a museum. The submarine appears to be made of metal and has a cylindrical shape with a pointed nose and a flat bottom. It has a large gun turret on top and a small window on the side. There are two large pipes running along the sides of the submarine, which are likely used to control the movement of the gun. On the right side of the image, there is a sign with information about the submarine. In the background, there are several people looking at the submarine and admiring it. The museum has a high ceiling with exposed beams and a brick wall.
