For the cult of the Sun and attention the Incas Superiors to them existed the Akllahuasi or species of convents that concentrated young women, called "Virgins of the sun". His daily life was dedicated to service activities of the Important Incas, weaving and contemplation; They had no contact with the external environment. In the case of Ingapirca, its residences make up a very peculiar architectural unit, which is linked to the Temple and the Ceremonial Square through a narrow and rectilinear corridor whose ends end in beautiful double jamba trapezoidal doors, of which it remains, almost complete , that of the ceremonial square.
The orientation of this corridor is OE-NO / E-SE and it leads those who visit from the Ceremonial Square to another small internal kancha of the Akllahuasi, which as a terrace allows you to observe the Barranco, the Intihuayco and the entire valley on which you build the Temple of the Incas. From this site and following a labyrinth path you can enter the different residences and courtyards of this unit, but especially you reach the best preserved building of Ingapirca in which the niches are left (3 per side, 6 in the door and 7 at the bottom), the door, the original height of the walls, evidence of plastering, lintels and mooring stones for the roof. Thanks to this 10.95 m long by 5.45 m wide and 2.50 high ceilingless and 0.80 m thick walls, with evidence in situ, it has been possible to virtually rebuild all Ingapirca and interpret its architecture.
On the other hand, the akllahuasi corridor, after the latest archaeological astronomical investigations, has acquired a fundamental importance, as it would be the third and perhaps the most evident in Ingapirca (the first was in Pilaloma, the second among the Palaces) which, given its orientation, location and architectural details, allows to demonstrate with surprising precision the phenomenon of the summer solstice, that is to say on June 21 of each year in Ecuador.
