The picture is the 138th Rifle Division Command Post, i.e., Lyudnikov's command post. There is a fence around the front, but it does not go all the way around the building. The picture you posted is taken from the rear of the building (i.e,. the cameraman is looking northwest).
I have tons of pictures of Stalingrad from when I visted the city as part of the 60th Anniversary of VE Day in May 2005. If I could figure out how to post some of them, I would gladly do so.
