Tiwanaku
Tiwanaku, also Tiahuanaco was the name of both the capital city and the empire that ruled in modern-day Bolivia, Peru, Chile and Argentina from 375 to 1000 A.D. It was centered near Lake Titicaca.
It has been speculated that the city could in fact be much older than originally presumed, as it was once a port town, sitting on the banks of Lake Titicaca, some 15 miles away. It is one of the best sites for pre-Columbian South American art, and many of the fine stone carvings and much of the masonry is of a higher quality than the Inca's or other South American civilizations which existed ofter the Tiwanaku. Arthur Broznansky, who did approximately fifty-year study of the ruins of Tiahuanaco, speculated that the city was as much as 17,000 years old, and that it had existed in the time of the great flood.[1][2][3]
