Peru's Andean Jungle Is Hiding A City That Turns Out To Be Four Times Larger Than Anyone Knew

Archaeologists must have one of the coolest jobs ever—as long as a lifetime of digging around in the dirt yields some epic results, like priceless artifacts, treasure-filled tombs, or groundbreaking insights into how ancient civilizations rose and fell. One team of researchers was lucky enough to have such a breakthrough in the remote Peruvian Andes, unearthing over 100 structures tied to the Chachapoya or “Warriors of the Clouds,” a people who resisted conquest by the Inca Empire for centuries.

Situated about 300 miles north of Lima in Rio Abiseo National Park (a UNESCO World Heritage Site), the Gran Pajatén complex contains remnants of the Chachapoya civilization. These ancient people flourished in the northeast Andes between the 9th and 16th centuries, repelling invasion by the powerful Inca Empire for hundreds of years, far longer than other groups, before finally being conquered. Sites like Gran Pajatén, all but inaccessible because of its far-flung location, high altitude and dense foliage, helped earn the Chachapoya the nickname “Warriors of the Clouds.” Image credits: World Monuments Fund / wmf.org The Gran Pajatén site, first discovered in the ’60s, stagnated after archaeologists recorded 26 structures in the 1980s. This most recent trove of discoveries, announced by the World Monuments Fund (WMF) last month, represents a great leap forward for the study of the mysterious Chachapoya. “Although specialists suspected that the extension of Gran Pajatén was greater, our findings were unexpected—not only in terms of scale, but in how they reframe the role and significance of the site,” said Juan Pablo de la Puente, executive director of WMF in Peru.

Certain at-risk buildings have been treated with a specially formulated, clay-based mixture to reinforce stone structures without changing their original layout. Even though they’ve already mapped hundreds of new structures, the researchers have only processed 10% of the LiDAR data. “What excites me most is that we’re only scratching the surface,” says de la Puente. “The path ahead is full of possibility, and we’re just beginning the journey.” Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org Image credits: World Monuments Fund / wmf.org
