I was wondering if you got a picture of this particular stone. =) That's really some amazing stone work.

There is a mystery on the function of excrescences, very visible on three different stones. Some say that they served for the alignment of the wall. But it is illogical, because we don't recover some to every corner of wall. There is an esoteric significance that nobody understand...

By 'excrescences' you mean the bumps on the lower parts of those stones. You'll have to excuss me, but that isn't a word I use everyday. ;-)

Yes, Excuse me for my bad english...

Amazing. I wonder how many people appreciate what a mystery it is that these rocks were cut to fit exactly, without modern tools, were assembled using no mortar and brought to the the top of a mountain to create a whole fortified town. Good pic too! ;)

Thanx Catflavor. Yes, Peru is magic!

I'm a sucker for stones and walls. ^_^ The texture is so nice.

incredible workmanship in that wall. what a remarkable people were the Incas.
