Also, near Sachsaywaman, another ancient architecture site called Q'Enko shows off the ancient civilizations interest in massive tone blocks, careful carving and sitting, and vitrified surfaces. Again, the years have not been kind to the underground areas or interiors of the buildings. Erosion and collapse have opened up chambers and tunnels to the air and weather.
As with most ancient locations, the exact purpose and use of Q'Enko is mostly a matter of guesswork and supposition on the part of the historians who research it. The construction, carvings, and chambers included in the structures seem to indicate that the location once contained a canal system. Also, a central chamber with altars and tables, which are assumed to be religious or funerary locations, shows considerable vitrification.
