Located in the eastern part of Serra dos Passos, in Regato das Bouças there are 14 rock shelters from the Neolithic period, some discovered very recently, in 2010.
In these shelters, it is possible to observe emblematic pictorial motifs – abstract painted in burgundy red, anthropomorphic «bar» type or with open arms in burgundy red and motifs composed of circles filled in red and two sets of three arboriforms arranged in a pyramid.
Buraco da Pala is a rock shelter that crowns one of the tops of Serra de Passos and extends to half the slope on the east side. The shelter was subject, between 1987 and 1990, to archaeological excavation campaigns that allowed the identification of four distinct phases of occupation, from the Neolithic to the Chalcolithic. The estate is in the inventory phase with the intention of being integrated into a museum space.
