Machu Picchu before it was a tourist attraction

Mapping tourism at Machu Picchu

Only 750 people lived at Machu Picchu at its height, but today, almost ten times that number trample through its delicate plazas and agricultural terraces every day. This data visualization vividly illustrates the skyrocketing numbers of visitors to Machu Picchu over the decades, and highlights the risks of over tourism, including soil erosion and other environmental threats, and negative social and economic impacts.

Machu Picchu explained

High in the Andes Mountains, Machu Picchu stands as a testament to the ingenuity and resilience of the Inca Empire. Constructed in the mid-15th century during Emperor Pachacuti’s reign, this site is believed to have served as a royal retreat or ceremonial center. Its engineering marvels, including sophisticated aqueducts, terraced farming systems, and precisely carved stone structures like the Sun Temple, highlight the advanced skills of the Inca civilization.

The original article revealing Machu Picchu to the world

After first coming upon the ruins of Machu Picchu in 1911, Hiram Bingham’s subsequent expeditions were funded by Yale University, the Peruvian government, and $10,000 from a then-young National Geographic Society—in fact, it was the first archaeological grant that NatGeo ever issued. The magazine devoted its entire April 1913 issue, all 192 pages, to Bingham and his findings. You can read that issue in its entirety here.

The unsolved mysteries of Machu Picchu

Who lived there? How did they get all that granite up there? Who were the 100 bodies found buried here, and why did some of them have elongated heads? Explore eight of Machu Picchu’s unanswered questions while scrolling through panoramic, clickable street-view images of the site, in this guide from Google Arts and Culture.

The explorer who re-discovered Machu Picchu

If there was a real-life inspiration for Indiana Jones, it may well have been Hiram Bingham, the Yale University historian who set out to find the rumored “lost city” of the Inca. This short feature from the BBC’s History magazine explains how this son of missionaries brought international renown to the site and to himself. In the process, he sparked an international feud that would last more than a century.

Machu Picchu, 101

Machu Picchu was built right on top of two intersecting fault lines, which makes it even more baffling how its temples and terraces have survived for more than 500 years—especially since no mortar was used to hold the precisely cut stones together. As this three-minute NatGeo video explains, this ingenious construction method allows the stones to bounce in place when earthquakes hit, shaking and rattling but rarely collapsing.

A virtual reality experience of Machu Picchu

If you can’t make it to the Andes, this virtual-reality experience—created using 360-degree cameras, and 3D modeling and sound design—is the next best thing. It lets you explore all the site’s major landmarks, including the Sun Temple and the Temple of the Condor, while listening to the sound of the wind whipping through the ruins, birdsong, and audio commentaries from expert guides.

Yale returns Inca artifacts to Peru

From the time he came upon Machu Picchu in 1911, Hiram Bingham began removing artifacts and human remains from the site and bringing them back to Yale University. Yale's Peabody Museum held them for 100 years, despite demands by the Peruvian government and the public that they be repatriated. Finally, in 2011, Yale returned thousands of items, including ceramics, jewelry and human skeletons.

Inca trail interactive map

Machu Picchu gets all the attention, but it’s definitely not the only Inca ruin in the area. Some dedicated trekkers opt to see the sites through a multi-day hike down the Inca Trail, which spans 26 miles from the Sacred Valley to Machu Picchu and reaches elevations as high as 13,800 feet above sea level. This 3D tour gives a sneak-preview of the ruins along the route, and the intense topography.

Machu Picchu, sacred backdrop for your dating app pic

Anyone who’s been on Tinder or Hinge in the last decade has noticed it: the obligatory Machu Picchu selfie, almost as ubiquitous as those photos of men posing with a fresh-caught fish. How did Machu Picchu, of all places, become a dating-app cliche? This satirical essay from McSweeney’s doesn’t answer that question, but has a great time poking fun at it.

Teotihuacán was already ancient when the Aztecs encountered it

Some vacationers flock to the sites of tragedies

Auschwitz, Chernobyl, Gettysburg, and more have all become tourist destinations, despite the horrible events that have occurred at the sites. The phenomenon is sometimes called "dark tourism," a trend that seems to be spurred by interest in history, morbid curiosity, and popular culture (like HBO's series "Chernobyl").

Revisiting the ornamental hermit craze of the 1700s

One of the more elaborate gardening trends of the 18th century was the placement of a well-designed hermitage within the landscape, a throwback to the more religious antiquity and the Middle Ages. The trend went so far for some that they hired real live hermits, preferably older, bearded, and willing to stay quiet and out of the way. Read about the wild trend here.

Thomas Cook invented modern tourism

In the mid-1800s, Cook took wealthy Britons on tours of Europe, Africa, the Middle East, and the US, often packaging together transportation, lodging, and food, effectively creating the modern travel agent. He also pioneered travel writing, with “Travellers Handbooks” offering tourists tips for visiting various countries.

Picasso was initially ignored by the US art market

Picasso’s now-iconic style was radical for its time and, as such, was something the US art market initially ignored.
