While I have only been to Machu Pichu vicariously, I have long admired the skills and can-do spirit of Inca stonemasons who made sturdy walls from precisely aligned stones of various shapes. Precise alignment is a lot harder with stone than with fruit.
The exquisitely crafted walls of Machu Pichu’s now-roofless buildings have endured centuries of frost heaves and neglect. What high purposes might the buildings have served? Were any of them schools or hospitals or research institutes?
Nope. The buildings were summer homes for the emperor and courtiers top 0.1% and temples think tanks for the priests pundits who told them that their wealth and privileges were rewards for pleasing the gods creating jobs. Machu Pichu endures in more ways than one.
Remember in November.
