Kalasasaya

Pada abad ke-17 Masehi, seorang pastur bernama Bernabé Cobo pergi ke Tiwanaku. Catatan yang ia buat memuat informasi detail mengenai arsitektur Situs Kalasasaya pada saat itu:"These stones show that a long period of time certainly mus has transpired. The rains have sufficed to wear them away to great extent. Where the line of the wall I spoke of runs, one sees many of these large standing stones set in the earth that served at buttresses. And though all of them were of the size that I have stated and cut with four corners , some of them are so worn down that they are no more than one estado high, and some are even smaller. The Part of them which has remained above the ground hardly shows any signs of having been worked. They look rough and pointed. Moreover, it is evident that the rains have disfigured towards the base, the original workmanship that they can be observed. And this cannot have happed in a short time. Certainly these stones have endured for many centuries because the rains could not have damaged them so much in any other way", dalam Vrancih (1999) hlm 45-46.
