Machu Picchu's stone buildings stand on a steep Andean ridge shaped by heavy rain, unstable slopes, and earthquakes. Discover how Inca builders used terraces, layered drainage, a 749-meter spring canal, sixteen fountains, and carefully fitted masonry to manage the site. The episode also explains what remains uncertain about the site's purpose and why 1911 brought international publicity rather than the discovery of a place already known locally. Inside this episode: - Building on a narrow Andean ridge - A 749-meter spring canal and sixteen fountains - Surface and subsurface rain drainage - Terraces as slope-stabilizing infrastructure - Stonework, earthquakes, and the site's uncertain purpose Sources include UNESCO, the American Society of Civil Engineers, and peer-reviewed surveys of Machu Picchu's water, drainage, and foundations.
