The Museum's wide variety of Incan artifacts represents the breadth of their empire. Inca maintained ethnic diversity throughout their vast territory, ruling over different regions and maintaining a smooth flow of people and goods with the help of a sophisticated road system.
Inca were talented masons, as seen in their stone models and architecture. In some cases, the masonry is so finely jointed that a knife blade does not fit between the stone joints.
