Divide the city into two halves, Hanan (upper) and Hurin (lower), each with its own lineages, its own shrines and its own place in the rites.
Four roads from the square to the four quarters
Let the four royal roads to the four quarters of the empire begin in the great square of the capital, so that the city is the centre from which the whole realm is divided.
The Inca empire was called Tahuantinsuyu, “the four parts together”: Chinchaysuyu to the north-west, Antisuyu to the north-east, Collasuyu to the south-east and Cuntisuyu to the south-west. Garcilaso says the division was made from the city of Cuzco, which he calls the navel of the world, and the four great roads left from its square toward each quarter. The ushnu in the square marked the point of origin.
Related rules
Settle the lords of every province in a ward of the capital lying on the side of the city toward their own province, so that the city holds the order of the whole empire.
Surround the great square with the houses of the kings, each opening onto it by a great hall large enough to hold a festival under cover when it rains.
Build every household, palace and temple as a kancha: a rectangular walled enclosure with a single doorway to the street, its single-room houses set against the walls and facing a central court; pair the kanchas back to back to make the blocks of the town.
