Massive Inca stones... achitectural wonder!

One afternoon after teaching my English classes, I headed into the central part of Cuzco and began wandering the tiny streets behind the cathedral.  Unexpectedly, I came upon ancient ruins of an Inca temple.  The rocks are massive and cut with the precision of a diamond cutter.

These stones, part of the Inca temple complex, are considered to be one of the most important Inca ruins in Cuzco ... important symbolically as well as for their precision with multiple angles..... 12 angles in all.
