Just a site visit as part of a larger trip in the country (some knowledge exchange stuff in a hydro power company i used to work for), so we were visiting several parts of the power plants down the Aconcagua valley among other areas. This was the highest point of that particular part of the trip.
This looks a lot like a house i lived in during my studies. We had to known down the rail… :))
ETA: i mean it REALLY looks like the same staircase, including the little door.
