So, I was just playing Minecraft on PS4 and I find this thing which seems so random. I would have posted a picture of it but I can't figure out how! It's just a wall built out of cobblestone and spruce wood/planks. Then there are 2 large windows. It's not very wide and it is very skinny but it's super tall! If it helps it was right outside a small rooftop forest and next to a river. I mined under it, through it, and on the sides and there were only sand and dirt blocks as I assumed. I have never seen anything like it before! Does anyone know what it is? Is it suppose to indicate something?
