  • While the Tambo is referred to and treated as a distinct building unique to the Inca, the game's data files reveal that it is actually an ordinary Trading Post with its name changed, a distinct appearance, and modified statistics.


The Inca Empire utilized an extensive system of roads to facilitate travel and transport throughout its vast territories. During the late 15th century, the Inca constructed over 10,000 tambos--administrative buildings that were staffed by locals conscripted through the mit’a corvee system--along these roadways. Tambos contained quipu records; they also served a military purpose, storing supplies and quartering soldiers stationed nearby or passing through the region.

Tambos sometimes housed Inca functionaries, or even served as economic or religious spaces. Critically, they also were transit stations for the Chasquis, messengers responsible for relaying orders and information throughout the Inca Empire. A capable Chasqui could travel from tambo to tambo within the space of a day and be assured of food and lodging for maximal efficiency. The system was deemed so effective that the Spanish conquerors adopted and expanded it.
