What the heck IS this place? It's enormous, but it's all just fricking empty walls and spaces. There's nothing left here that looks like it was an abandoned city, rather, it's just enormous EMPTY WALLS.
This isn't some babylonian city, this was the largest city in south america only 400-500 years ago!! Something like the huaca de luna is twice as old as this place, yet still retain colorful painted walls and remnants of its time.
BUT THIS IS JUST MILES OF EMPTY WALLS. I've never seen this with a prehispanic city before.
