It was the palace of the Inca Pachacútec. Already in the colony this palace was chosen by Francisco Pizarro to build his home.
Qasana is a Quechua word whose meaning is "icy place" or "where the frost falls". In Inca times it extended from the roads parallel to the Saphy river to the palace of Qoraqora and its front faced the Wacaypata, the interiors of it faced the neighborhood of the schools.
According to historians, this was the palace of the Inca Pachacutec and the residence of the royal lineage "Iñaka PanaKa Ayllu". Already in the colony this palace was chosen by Francisco Pizarro to build his home.
The Qasana was located in the sector of what today is the Plaza de Armas and was adjacent to Procuradores, Tecsecocha, Amargura, Saphi and Plateros streets.
Currently you can see in the place colonial style mansions, which are mostly used for trade and tourism. The foundations of the Qasana, the residence of the greatest Inca ruler, can still be seen in its foundations.
