An Observatory

Actually, the thirteen stone towers standing on Peru's desert domain is nothing new, fact is...the world has known of it since the 19th century, but wait there is more. Research experts have discovered just last year regarding the very purpose of this structure- it was in fact a solar observatory, definitely among the earliest known. Interesting that it is only now that they focused on finding out, huh?

According to two renowned experts, the 13 Towers of Chankillo, corresponds very close to the rising/setting of the sun, this over a full year's period. Come December 15 (that's a solstice), sun would be directly overhead one of the towers.

Besides the tracking of the sun by the builders of the towers, whoever they may had been (it's still up for speculations), these structures were also designed to show their rulers' 'kinship' with this body of the solar system -the sun that is.

According to the same experts, if all they wanted was to measure the seasons, there would have been no need to erect such structures. On that I agree, but wait aren't we imposing our modern day thinking on very early cultures?
