The Daily Grail on the meaning of a mysterious, ancient marvel sitting in the South American desert:
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.
So archaeologists put forward a new interpretation…the site may have been a place of worship and a solar observatory, like Stonehenge, rather than a fort. Their main evidence was that the towers line up with the sunrise on important dates such as summer and winter solstice.
