The US senator who found a city in the sky

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.

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 Machu Picchu we know today is familiar thanks to its neatly manicured plazas, lovingly preserved stone buildings, and ever-present hordes of tourists.

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.

Finally, in 2011, Yale returned thousands of items, including ceramics, jewelry and human skeletons.

Scientists are still confused how Machu Picchu was built

Machu Picchu, the 15th-century Inca city high in the Andes, continues to fascinate experts with its mysteries.
