Here’s what you’ll learn when you read this story:Archaeologists with the World Monuments Fund uncovered over 100 previously unknown archaeological structures in Peru’s Rio Abiseo National Park. The area in and around the park was the home of the Chachapoya civilization from the seventh through 16 th centuries. Plenty of its land is known to hold ancient discoveries, and archaeologists are still uncovering more. Recently, a team located over 100 previously unknown structures, all part of the Chachapoya civilization from sometime between the seventh and 16th centuries. The area was first rediscovered in the 1960s, and in the 1980s—the national park was officially founded in 1983—archaeological teams found 26 ancient structures.
