Monte Alegre State Park
Painted rock shelters above the lower Amazon that pushed back the accepted date for people in the region.
Updated 19 October 2026
The hills behind Monte Alegre carry painted shelters - Pedra Pintada, Pedra do Mirante and others - with figures in red and yellow of human forms, animals, handprints and concentric geometric designs, some of them positioned to catch the sun at particular times of year. Their importance is chronological. Excavation at Caverna da Pedra Pintada led by Anna Roosevelt in the 1990s produced dates around eleven thousand years old, which challenged the model that the Amazon was settled late and only by peoples moving down from elsewhere, and argued instead for early, independent occupation of the tropical forest. The park protects the hills, the shelters and a stretch of cerrado and forest above the floodplain. Access is guided and controlled.
History
The park grew out of studies by the Pará Institute of Economic, Social and Environmental Development at the end of the 1980s and was the first protected area in Pará created with the local community; it was established on 11 November 2001 over 5,800 hectares. In November 2012 researchers of the Museu Paraense Emílio Goeldi reported 19 newly found sites with rock paintings and pottery in its lower part, and on 3 January 2013 2,122 hectares were moved to the Paytuna Environmental Protection Area, leaving the park 3,678 hectares (Wikipedia, Monte Alegre State Park).
