Tiwanaku
Summary
Tiwanaku (Tiahuanaco or Tiahuanacu) is a Pre-Columbian archaeological site in western Bolivia, near Lake Titicaca, about 70 kilometers from La Paz, and it is one of the largest sites in South America. Surface remains currently cover around 4 square kilometers and include decorated ceramics, monumental structures, and megalithic blocks. The site's population probably peaked around AD 800 with 10,000 to 20,000 people.
The site was first recorded in written history in 1549 by Spanish conquistador Pedro Cieza de León while searching for the southern Inca capital of Qullasuyu.
Jesuit chronicler of Peru Bernabé Cobo reported that Tiwanaku's name once was taypiqala, which is Aymara meaning "stone in the center", alluding to the belief that it lay at the center of the world. The name by which Tiwanaku was known to its inhabitants may have been lost as they had no written language. Heggarty and Beresford-Jones suggest that the Puquina language is most likely to have been the language of Tiwanaku.
The dating of the site has been significantly refined over the last century. From 1910 to 1945, Arthur Posnansky maintained that the site was 11,000–17,000 years old based on comparisons to geological eras and archaeoastronomy. Beginning in the 1970s, Carlos Ponce Sanginés proposed the site was first occupied around 1580 BC, the site's oldest radiocarbon date. This date is still seen in some publications and museums in Bolivia. Since the 1980s, researchers have recognized this date as unreliable, leading to the consensus that the site is no older than 200 or 300 BC. More recently, a statistical assessment of reliable radiocarbon dates estimates that the site was founded around AD 110 (50–170, 68% probability), a date supported by the lack of ceramic styles from earlier periods.
Tiwanaku began its steady growth in the early centuries of the common era. From approximately 375 to 700 AD, the city grew to significance in the Andes. At its height, the city of Tiwanaku spanned an area of roughly 4 square kilometers (1.
