Pre-Columbian period

The oldest traces of human presence in Quito were excavated by American archeologist Robert E. Bell in 1960, on the slopes of the Ilaló volcano, located between the eastern valleys of Los Chillos and Tumbaco. Hunter-gatherers left tools of obsidian glass, dated to 8000 BC. This archeological site, called EI Inga, was brought to Robert Bell's attention by Allen Graffham. As a geologist in Ecuador, Graffham pursued his amateur interest in archeology. He made surface collections at the site during 1956. The discovery of projectile points, particularly specimens with basal fluting, stimulated his interest, and he made several visits to the site to collect surface materials. Graffham's previous interest in Paleo-Indian remains, and his experience with early human-made materials in Kansas and Nebraska in the Central Plains of the United States, led him to believe that the site was an important discovery.

The second important vestige of human settlement was found in the current neighborhood of Cotocollao (1500 BC), northwest of Quito. The prehistoric village covered over 26 hectares in an area irrigated by many creeks. Near the ancient rectangular houses, there are burials with pottery and stone offerings. The Cotocollao people extracted and exported obsidian to the coastal region.

The priest Juan de Velasco wrote about a Kingdom of Quito. His source was a lost work by Marcos de Niza, the existence of which has not been confirmed. His account said that another people, known as the Cara or the Schyris, came from the coast and took over the entire region by AD 890. He goes on by saying that this kingdom lasted until the Inca took over the territory in the 15th century. However archeological evidence does not indicate unity among the different ethnic groups in the region. The local Quitu or Quillaco tribe is distinct in its art and architecture from its neighbors.

By the 20th century, many prominent historians who began more academic studies, doubted the account of the Quitu-Cara kingdom. They think it was a legendary pre-Hispanic account of the highlands.

These days most historians deny the existence of the kingdom of Quito in favor of a more fragmented region. The Quitu ruled over Quito at the time of the Inca invasion by Topa Inca Yupanqui under the reign of his father. In the early 21st century, there were spectacular new finds of 20-meter deep tombs in the La Florida neighborhood of Quito. Dating to AD 800 they provide evidence of the high quality of craftsmanship among the Quitu, and of the elaborate and complex character of their funerary rites. In 2010 the Museo de Sitio La Florida opened to preserve some of the artifacts from the tombs and explain this complex culture.
