Huge carved rocks at Ollantaytambo Ruins (with our tour guide in front). The rocks for the site were quarried from a mountain on the other side of the mountain (6km away, and across a river). The Spanish conquistadors destryoed all of the carvings that were on these flat rocks.
Looking down from the top of the Ollantaytambo Ruins.
These walls inside the Ollantaytambo Ruins aren't as ornate as the others - most likely this means they were for sleeping quarters or something else that wasn't sacred.
