Parque Nacional Serra da Capivara

Serra da Capivara preserves evidence of one of the longest continuous sequences of human habitation in the Americas, with archaeological traces potentially reaching back tens of thousands of years. The rock art documents at least twelve millennia of cultural expression by prehistoric peoples of northeastern Brazil, while the park's creation in 1979 and UNESCO inscription in 1991 reflect one archaeologist's extraordinary half-century campaign to protect this heritage.

No origin myth survives from the cultures that painted these shelters. The people who created the Nordeste and Agreste traditions left no written record, no oral history that endured through the intervening millennia. What they left is the rock art itself, and through it, a visual account of how they lived, hunted, celebrated, and perhaps prayed.

The modern story of Serra da Capivara begins with Niede Guidon, a Franco-Brazilian archaeologist who first encountered photographs of the rock paintings in the 1960s and traveled to Piaui in the early 1970s to see them firsthand. What she found stunned her: not a handful of scattered sites but hundreds, then thousands of painted shelters spread across a vast sandstone landscape in one of Brazil's most neglected regions. She dedicated the rest of her life to their study and protection.

Guidon's work was revolutionary and controversial in equal measure. Her team's excavations at Pedra Furada yielded charcoal and possible stone tools that she dated to fifty thousand years before present, a claim that would, if accepted, rewrite the story of human arrival in the Americas. The mainstream archaeological community pushed back hard, arguing that the charcoal could result from natural fires and the stones from natural fracture. The debate continues, unresolved. But whether or not the earliest dates hold, the securely documented record of human presence here, reaching back more than twelve thousand years, is extraordinary by any standard.
