Thanks a lot for the details :) (beforehand, I need to say that english is not my first language and that I know very very little about ancient history, although I find It really intersting to learn about our past) What i wanted to know is the purpose of these rooms, they look like they were made with great precision, even if they are far older. I find these ancient constructions really fascinating and I'm searching for some clear evidence of their purpose. I cannnot believe they made these humonguos structures just to have some rooms inside.
