The distance from the city of Cuzco to the city of La Paz is eighty leagues, a little more or less. It must be known that, before La Paz was founded, all the towns and villages now subject to that city were within the limits of the city of Cuzco. Setting out from Cuzco by the royal road of Collasuyu, it leads to the narrow pass of Mohina, leaving the buildings of Quispicanchi on the left hand. The road goes by this place, after leaving Cuzco, and is paved with stones. In Mohina there is a large swamp, across which the road is carried on a paved causeway. There were great edifices in Mohina, which are now in ruins. When the governor Don Francisco Pizarro entered Cuzco with the Spaniards, they found much gold and silver, and rich and precious clothing in these edifices. I have heard some Spaniards say that there was a block of stone in this place, in the shape of a man, with long ropes, and beads in the hand, besides other figures, some of which they adored as idols.

Beyond Mohina is the ancient village of Urcos, which is about six leagues from Cuzco. On this road there is a very large and strong wall, and the natives say that along the top of it a channel of water was conducted with great labour from a river, with the same skill and order as they make their other irrigating channels.
