The Côa Valley, in central Portugal, is considered one of the most important rock art locations in the world. More than 70 sites can be found here, still in their original positions, displaying breath-taking engravings from prehistoric, protohistoric and historic times. In the heart of this culturally significant area is the Côa Museum.
“Schist” is a type of crystalline metamorphic stone. It is easily split, creating a flat surface. For centuries, this “horizontal” stone became the ideal building material to create weatherproof, secure houses. Today, many original homes made of schist still stand and are remain occupied by the residents of the village.
