Prehistoric rock art
The valley near Vila Nova de Foz Côa, in northeastern Portugal, is home to extensive displays of underground and outdoor Paleolithic art — horses, aurochs (wild bulls), etc.
The site, which was originally to be covered with water from a dam, was designated a UNESCO World Heritage Site in 1998 and opened to the public. In the center is the museum Quinta da Ervamoira, showing bread making and wine producing.
