Mysteries of Machu Picchu Revealed

High in the Andes sits a stone city that seems built to touch the clouds. Machu Picchu.

But who built it, and why? In the mid-1400s, Inca emperor Pachacuti ordered its construction.

It wasn’t a city for everyone, it was a royal estate and sacred retreat. Only nobles,

priests, and chosen attendants lived and worked there. The engineering

was incredible. Huge granite blocks were cut so precisely they locked together without mortar.

That’s why the walls still stand after centuries of earthquakes. The Inca carved terraces for farming,

built aqueducts for fresh water, and aligned parts of the site with the sun’s path.

Fun fact: no wheels were used to move the stones, workers dragged them with ropes.
