Listen Later

How do you lose an entire city in the mountains—and then find it again centuries later? In this episode, Gordy explores Machu Picchu, the legendary Incan citadel perched high in the Andes Mountains, hidden from the outside world for over 400 years.

We’ll uncover how the Inca built this architectural wonder at 8,000 feet, without wheels, iron tools, or written records—and how a Yale professor accidentally brought it to global fame while looking for something else entirely.

From stonework that defies earthquakes to solar temples that still align with the solstice, this isn’t just a lost city—it’s a masterclass in ancient innovation, spiritual design, and altitude-fueled determination.

Gordy also shares personal stories from visiting the site—llamas, coca leaves, and old military helicopters included.

Don’t miss this deep dive into one of the world’s most breathtaking mysteries.
