This complex is the most important archaeological center in the valley of Urubamba, after Ollantaytambo and Pisac. The ruins are impressive, although the conservation of the site is inferior to that of Ollantaytambo or Pisac, because they are older.
But unlike the places mentioned above Huchuy Qosqo has a peculiar architecture: the buildings have been built on polished stone bases of fine finish, with clay plaster (they are the best preserved parts) and the highest floors are made of adobe.
One can observe a kallanka (rectangular enclosure that could measure up to 70 meters long and that were important state centers where the Inca officials stayed) of at least 40 to 50 meters long. Also a remarkable building with two floors of stone and an upper one of adobe.
