The image shows an old cannon on display in a museum. The cannon is made of metal and has a long, cylindrical body with a pointed tip. It is mounted on a large wooden wheel with spokes radiating outwards from the center. The wheel appears to be old and weathered, with some rust and discoloration visible on the surface. In the background, there are other cannons and a building with large windows. The floor is tiled and there is a yellow caution tape next to the cannon.
