The Inca administration that developed in the city of Cusco and the other administrative centers was based on a growing state bureaucracy. In the capital of the empire sumptuous temples and palaces were raised, the Inca squares were immense and had a trapezoidal shape.
In these squares an intense social, religious and Inca administration activity was carried out. And the architect of this was the Inca Pachacútec who designed the great city of Cusco that the chronicles collected, he designed the city from scratch and it was organized based on a large open space that was the Plaza el Huacaypata, the current central square of the Cusco was a single great space, which had around the most important and emblematic buildings such as the Inca palaces and buildings of religious and organizational sense.
In the square was the ushnu, a pyramidal construction to preside over the most important ceremonies of the Tahuantinsuyo by the Inca, it was probably located in the area where the cathedral is now and the suntur wasi was so it was probably a circular building in front of what was then the Amarucancha, which was also an Inca palace.
Among the main officials of the Inca administration was the inspector or overseer called the “Tucuy Ricuy” also known as “the one who sees everything” or “the eyes and ears of the Inca.”
The “Quipucamayoc” were in charge of the quipus that were used to count, in addition to being a form of writing, the Incas seem to have assimilated not only artistic aspects but also agricultural and construction techniques from the Wari empire.
