The image shows a large artillery cannon on display in a museum. The cannon is mounted on a pedestal and is black in color. It has a long, cylindrical barrel with a pointed tip and a handle on the side. The body of the cannon is made of metal and appears to be old and weathered. There is a small plaque on the pedestal with information about the cannon. In the background, there is a painting hanging on the wall and a door leading to another room.
