Two builders working in Kuala Lumpur vied to outdo each other's grandeur; but one tower is straight, and the other one ain't. So, I guess we know who won that war.
These are restorations of the stone portions of a cylindrical houses. These would have been topped with a conical thatched roof, though less is known about the details (e.g. pitch) of such roofs because the thatching (obviously) didn’t survive as well as the stone bases. These were located at an archeological site on the road between Cuzco and Puno.
