In the coastal desert of Peru lies a strange structure consisting of what appears to be a fort atop a hill, but with a vertebrae-like line of 13 towers constructed on a raised area to its south-east.
The fort is odd from a military point of view because it would have been almost impossible to defend: it has numerous entrances and no source of water inside. Then there are the towers, which are several hundred metres from the hilltop fort, lie in a straight line and serve no discernible defensive role.
