Sacsahuanan
Pronounced "sexy-woman" this site was one of the most important places for the Incas. On the first day of summer the Emperor, priests and common people (standing area only) would gather to ask the sun god to return. The Emperor would address the masses and a llama would be sacrificed. This site has the largest and most impressive stonework in the Empire. The vast and impressive site was only used once a year.
