I find this wall fascinating as an architect. It’s the wall of a house in the borders of Juliaca city. I can guess that it’s a house made with adobe but with time the owners get more wealthy so they covered it with concrete and replaced the old window with a modern one, reflexive and almost frameless. The woods almost hidden are the structure to support a wooden floor. The difference in the texture indicate that after the first covering with concrete and the shape suggest that the owners thought in a kitchen, laundry or bathroom so it was needed to pick the concrete to new installations.
I find this wall interesting because I like contrasts, that piece of sky counterposed to the rustic concrete.
