Honestly, the story of how Machu Picchu became a household name is a bit of a mess. Most of us grew up with this image of Hiram Bingham, the fedora-wearing Yale professor, hacking through thick jungle to "discover" a lost city. It’s a great narrative. It’s also mostly a myth. If you look back at the National Geographic Machu Picchu archives—specifically that massive, 184-page April 1913 issue—you start to see the cracks in the Indiana Jones vibe.
Bingham didn’t stumble upon an empty, forgotten ghost town. He was led there by a local farmer named Melchor Arteaga and a 10-year-old boy. There were families living on the terraces, growing crops in the same soil the Incas had tilled centuries before.
The 1913 Issue That Changed Everything
When National Geographic decided to fund Bingham’s 1912 and 1915 expeditions, they weren't just backing a hike. They were creating the first viral travel campaign in history. Before the April 1913 edition, Machu Picchu was a local secret or a footnote in Peruvian history. After that issue hit doorsteps with over 250 photos, it became the "Lost City of the Incas."
The magazine did something brilliant. It framed the site as a mystery. It used phrases like "wonderful city of refuge" and "cradle of the Inca empire." People ate it up. But here’s the kicker: Bingham was actually looking for something else. He was hunting for Vilcabamba, the real last stronghold of the Inca resistance against the Spanish. He convinced himself Machu Picchu was it, even though he’d actually visited the real Vilcabamba (Espíritu Pampa) and dismissed it because it wasn't "grand" enough for his photos.
What the Experts Got Wrong (and Right)
For decades, we relied on the theories published in those early National Geographic reports. Bingham thought the site was a "holy nunnery" because he found a bunch of skeletons that his team identified as female.
He was wrong.
Modern osteologists, like John Verano from Tulane, re-examined those same bones recently. Turns out, the skeletons were a pretty even mix of men and women. The "Virgins of the Sun" theory was basically a colonial-era guess that happened to sound romantic in a magazine.
So, what was it actually?
Current consensus among archaeologists, including the folks National Geographic still sends out there today, is that Machu Picchu was a royal estate. It was built around 1450 by the Emperor Pachacuti. Think of it as a 15th-century Camp David. It was a place for the elite to hang out, perform religious ceremonies, and show off their engineering chops.
The Engineering Nobody Talks About
We always focus on the "Temple of the Sun" or the "Intihuatana" stone, but the real genius of Machu Picchu is the stuff you can’t see.
The Incas were obsessed with water. They built an underground drainage system so sophisticated that the site hasn't washed away despite getting over 70 inches of rain a year. National Geographic’s more recent research highlights how the terraces aren’t just for looks; they act as a massive filtration and stabilizing system.
They also didn't use mortar. The ashlar masonry—where stones are cut to fit together perfectly—is an earthquake hack. When the ground shakes, the stones "dance" and then settle back into place. Without that, the whole thing would have been a pile of rubble centuries ago.
The Artifact Controversy
You can't talk about the National Geographic Machu Picchu legacy without mentioning the 40,000+ artifacts Bingham took back to Yale. We’re talking bones, pottery, and silver. For nearly a century, Peru wanted them back. Yale argued they were "excavated for science."
It took until 2012 for the final shipment of those artifacts to return to Cusco. It was a messy, high-stakes legal battle that forced a lot of institutions to rethink how they treat cultural heritage. If you visit the Casa Concha Museum in Cusco now, you can see the stuff Bingham packed into crates over a hundred years ago.
Why It Matters in 2026
If you’re planning a trip today, the experience is radically different than what you saw in those grainy 1913 photos. As of June 2024, the Intihuatana (the "hitching post of the sun") is closed to direct public access because too many tourists were literally wearing the stone down.
The site now uses a strict circuit system. You can’t just wander around for eight hours anymore. You get a four-hour window, and you have to follow a specific path. It feels a bit clinical compared to the "explorer" days, but it’s the only way to keep the mountain from collapsing under the weight of 1.6 million visitors a year.
Practical Tips for Your Own Expedition
If you want to experience the site without the crowds, you've got to be smart.

- Book the "Circuit 2" ticket if you want the classic postcard view. It’s the most comprehensive path.
- Avoid the 10:00 AM rush. This is when the train crowds from Cusco arrive. Either go at the crack of dawn (6:00 AM) or wait until the 2:00 PM slot when the light hits the stones perfectly and the crowds thin out.
- Visit the Machu Picchu Museum (Museo Manuel Chávez Ballón) at the base of the mountain. Most people skip it, but it’s where you actually learn how the site was built.
- Don't call it a "Lost City." Locals find it a bit insulting. It was never lost to them; it was just "undocumented" by the West.
The National Geographic legacy is complicated. It gave the world Machu Picchu, but it also gave us a version of the story that was more Hollywood than history. Seeing the site today is about peeling back those layers of 1913 romanticism and appreciating what the Incas actually did: they built a masterpiece that refused to be forgotten.
Actionable Next Steps
Before you book your flight, check the official Ministerio de Cultura website for the latest circuit maps. The rules change often—recently, new routes were added specifically for those wanting to hike Huayna Picchu versus those just wanting the city ruins. Also, ensure you have a registered guide; they are technically required for entry and are the only ones who can point out the subtle "dancing" stones and hidden drainage channels that make this place an engineering marvel.
