This big rock has a building around it.
It was probably considered sacred.
It is now, anyway. People leave coca leaves at its base as offerings. Sometimes under little piles of rock.
It is a very big and impressive looking rock.
The walls around it are not very impressive, so it was either a very old temple or not a very important one.
But one big wall leading up to it uses gigantic stones that are carved to fit into each other.
