The Côa Valley (Portugal) is a UNESCO World Heritage Site, inscribed in the WH List in 1998 under the official name of “Prehistoric Rock-Art Sites in the Côa Valley“. According to WHC: this exceptional concentration of rock carvings from the Upper Palaeolithic (22,000–10,000 B.C.) is the most outstanding example of early human artistic activity in this form anywhere in the world.

From ArchDaily:

The Museum of Art and Archaeology in the Côa Valley is conceived as an installation in the landscape. The monolithic triangular form is a direct result of the valley’s confluences. Its materiality evokes the local stone yards and reflects two different natures: the concrete’s matter, and the local stone’s texture and colour.

Architects: Camilo Rebelo + Tiago Pimentel/Sandra Barbosa
