Reconstruction of a local Inca dwelling uncovered near Rancagua
These buildings were wasis (Quechua for "house"). They functioned as administrative and residential centres, and activity at the site revolved around these structures. Food was cooked here, especially quinoa, the staple diet of the Incas. They identified it with their homeland and it was grown to symbolically alter the landscape and confirm domination over the local populations. They also cooked and ate Madi seeds here. A large number of cactus remains were also uncovered in the aisle by these buildings. This tells us that this passage way was lit by torches, which were made from cactus stalks.
