Central Plaza

At the back of the Intihuatana is another staircase. It descends to the Central Plaza, which separates the ceremonial sector of Machu Picchu from the more mundane residential and industrial sectors, which were not as well-constructed. At the lower end of this latter area is the Prison Group, a labyrinthine complex of cells, niches and passageways both under and above the ground.

The centerpiece of the group is the Temple of the Condor, which contains a carving of the head of a condor, with the natural rocks behind it resembling the bird's outstretched wings. Behind the condor is a well-like hole and, at the bottom of this, the door to a tiny underground cell that can only be entered by bending double.
