The image is of a brick building with a doorway. The building is made of red brick and has a few windows. There is a sign above the doorway that says "24a Block". There is a light fixture above the doorway, and the doorway is open and appears to lead into a dark room. The building is old and worn. There are some leaves and pebbles on the ground in front of the building. This is a building at the Auschwitz-Birkenau concentration camp.
