Wall Watching
We must’ve walked past this ancient Inca wall in Cusco about 4 times before we realized what we were passing. Not four blocks from our hostel is this remarkable example of Pre-Colombian architecture. 
I read that they used several techniques to made some exceptionally solid walls: they placed larger, convex stones at the bottom and smaller ones at the top, all doors and windows are trapedoizal in shape and the stones are carved to roughly the same trapedoiz-ish shapes.
In this pic, Marc is posing beside the famous “Stone of 12 Angles”, which was not only in the wall past which we walked several times, it was nearly constantly the focus of a tour group. Sometimes we can be so unobservant.
Indeed, they are so well made that they have withstood two major earthquakes 300 years apart and are still so solid that colonial and modern buildings use their Incan foundations. The way the stones fit together so tightly, without the use of mortar, is quite impressive. They say that some are so well fitted that not even a knife’s blade can slide between them. This church and cloistered convent is perched on top of what used to be part of the Sun Temple.
Besides wall watching, we spent some time examining Incan art and pottery.
