Janko Kala, the reader may recall, was one of the old Formative Period villages on the Taraco Peninsula. It was one of the four principal Middle Formative villages, and remained occupied through the Late Formative. It is described in more detail in Chapters 5 and 6. The village was relocated to the site of Titicachi (T-415) in the Tiwanaku period, and was abandoned in the Early Pacajes phase, In the Pacajes-Inka phase, the original site of the village was reoccupied.
At 6.50 ha, sector H at Janko Kala is clearly the largest LH village on the Taraco Peninsula. It has a population index value of 368. The site was probably the LH administrative center of the Taraco Peninsula, and compares favorably in terms of size to other significant Inka sites such as Guaqui. There can be no doubt, however, that it was subordinate to one of the major Inka centers in the Tiwanaku Valley or the Katari Basin.
