The larger stones are on the bottom. Each stone is carved to fit the others neatly, and no cement is used. Say what you want about autocracy, but the job gets done! Each stone must have taken someone years to carve (not that they complained).

At the time I was hugely annoyed that these people wouldn't get out of the picture. But the heads are a good guide to the size of the carved stones.

Opposite the stones. A bit of mystery as to what the purpose was behind this.

A fellow tourist from Lima.

Great travel companions. Both had their origins in Cuzco but grew up in Lima. In school they had studied everything about the area and knew every stone.

Going back in the evening. Our arrival was timely -- it interrupted the tour guide's very tedious monologue about the possible use of terra cotta in Inca sanitary habits.
