The image shows a large, triangular-shaped building with a pointed roof. The building appears to be made of brick or stone and has a small window on the top. The roof is covered in a dark grey shingled material, and there is a small chimney on the right side of the roof. In front of the building, there are several rows of cannons arranged in a neat row. The ground is made of gravel and there are a few other buildings visible in the background. The sky is overcast and the overall mood of the image is gloomy.
