Over 140 rock shelters with paintings spanning 12,000 years, from abstract geometric patterns to detailed human figures. The styles changed so dramatically that archaeologists debate whether different cultures replaced each other or ideas evolved.
A gallery of prehistoric styles
The Peruaçu River valley is a karst region in northern Minas Gerais, defined by limestone canyons and enormous caves. This region contains one of Brazil's most significant concentrations of prehistoric rock art, with some paintings dating back at least 12,000 years. The art is found in over 140 recorded archaeological sites, decorating the walls of rock shelters with a variety of images.
Archaeologists have organized the thousands of individual paintings into distinct stylistic sets. The São Francisco tradition is one of the most prominent, characterized by geometric figures. These are often bichromatic, using red and yellow, but also appear in combinations with white and black. Artists created complex grids and patterns of intersecting lines, with strokes similar in width to a human finger. Another major style, the Montalvânia complex, focuses on schematic human figures, often depicted with curvilinear limbs that suggest movement. These figures are typically less than 30 centimeters in height. The artists used mineral pigments, primarily iron oxides like hematite to create red colors and goethite for yellows.
Layers of meaning and mystery
The rock walls of Peruaçu are a layered canvas, showing how different artistic groups interacted with pre-existing work over millennia. The Lapa dos Desenhos is a principal site, with a single panel containing over 3,000 individual figures. Here, different styles are frequently superimposed, creating a complex chronological puzzle.
The relationship between the styles is a topic of scientific debate. Artists of the São Francisco tradition often painted directly within the spaces defined by earlier works, sometimes even retouching or adding elements to older figures. In contrast, later groups sometimes painted over previous art, obscuring what was beneath. This layering raises a central question: do these stylistic shifts represent the arrival of entirely new cultural groups to the valley, or do they show the artistic and cultural evolution of a single, continuous population over thousands of years? The answer remains unresolved. Some of the oldest art in the region comes from Lapa do Boquete, where excavations uncovered a buried boulder with engravings (petroglyphs) situated between sediment layers dated from 9,500 to 8,000 years BP.
💡Fun Facts
The name Peruaçu originates from the Tupi language, combining "Peru" (hole or fissure) and "Açu" (big), a direct reference to the region's massive caves.
The park contains the world's largest known stalactite, a 28-meter formation inside the Gruta do Janelão known as the "Perna da Bailarina" (Ballerina's Leg).
Some paintings are located high on shelter walls, suggesting the artists may have constructed scaffolding to reach them.
In addition to paintings, the sites also feature petroglyphs, which are images created by incising or pecking designs into the rock surface.
The park is open for guided tours, which must be booked in advance. Access is controlled and depends on guide availability.
Admission
There is no park entrance fee, but hiring a mandatory, accredited local guide is required for all visits.
Accessibility
Visiting the sites requires hiking on trails of varying difficulty, some of which include steep sections, uneven terrain, and large boulders. Good physical condition is recommended.
