The image shows an old cannon on display in a museum. The cannon is mounted on a wooden platform with two large wooden wheels. The wheels are made of wood and have a dark brown finish. The body of the cannon is made of metal and appears to be old and weathered, with visible signs of wear and tear. There is a large cannon barrel on the right side of the image, and a smaller cannon on the left side. In the background, there is a stone wall and a glass window, allowing natural light to enter the museum.
