Like many locations in Spaghetti Westerns, this was a pre-existing location not built for any one film. Today it is in ruins, it's roof collapsed and the walls beginning to crumble. Vegetation from the desert has also began to take over. Even as nature retakes this location, much of it can still be recognized from Day of Anger.

with the door missing, the roadway is only a few feet outside
Below is a comparison between when the movie was shot, my first visit in 2013, and my next visit 18 months later in 2015.
