Nestled high in the slopes of the Andes, the ruins of Machu Picchu continue to reveal the mysteries of the Inca Empire. While the archaeological site draws scores of visitors to Peru annually, here are 10 lesser known secrets hidden beneath its layers of history.

It’s not actually the Lost City of the Inca.

When the explorer Hiram Bingham III encountered Machu Picchu in 1911, he was looking for a different city, known as Vilcabamba. This was a hidden capital to which the Inca had escaped after the Spanish conquistadors arrived in 1532. Over time it became famous as the legendary Lost City of the Inca. Bingham spent most of his life arguing that Machu Picchu and Vilcabamba were one and the same, a theory that wasn’t proved wrong until after his death in 1956. (The real Vilcabamba is now believed to have been built in the jungle about 50 miles west of Machu Picchu.) Recent research has cast doubt on whether Machu Picchu had ever been forgotten at all. When Bingham arrived, three families of farmers were living at the site.

It’s no stranger to earthquakes.

The stones in the most handsome buildings throughout the Inca Empire used no mortar. These stones were cut so precisely, and wedged so closely together, that a credit card cannot be inserted between them. Aside from the obvious aesthetic benefits of this building style, there are engineering advantages. Peru is a seismically unstable country—both Lima and Cusco have been leveled by earthquakes—and Machu Picchu itself was constructed atop two fault lines. When an earthquake occurs, the stones in an Inca building are said to “dance;” that is, they bounce through the tremors and then fall back into place. Without this building method, many of the best known buildings at Machu Picchu would have collapsed long ago.

Machu Picchu 101

Built without the use of mortar, metal tools, or the wheel, Machu Picchu is an engineering marvel. But why was it built—and deserted?

Much of the most impressive stuff is invisible.

While the Inca are best remembered for their beautiful walls, their civil engineering projects were incredibly advanced as well. (Especially, as is often noted, for a culture that used no draft animals, iron tools, or wheels.) The site we see today had to be sculpted out of a notch between two small peaks by moving stone and earth to create a relatively flat space. The engineer Kenneth Wright has estimated that 60 percent of the construction done at Machu Picchu was underground. Much of that consists of deep building foundations and crushed rock used as drainage. (As anyone who’s visited in the wet season can tell you, Machu Picchu receives a lot of rain.)

You can walk up to the ruins.

A trip to Machu Picchu is many things, but cheap is not on
