These are ruins of the settlement of Andean peoples who managed to fight off or at least coexist with the Inca and resisted the Spanish for about 150 years until they were finally rounded up and sent on a death march to Buenos Aires in yet another infamous Spanish episode. The survivors give their name to the town/suburb south of the capital. The settlement is well fortified but has a large residential area. You can spend a few pleasant hours wandering around. There is a small museum and a great little cafe there.
