Main image

The Prehistoric Rock Art Sites in the Côa Valley and Siega Verde are an interlinked series of open-air Paleo- and later prehistoric rock engravings situated on river valleys in northeastern Portugal and western Spain. The sites contain a large corpus of animal and human motifs incised on exposed rock faces and are inscribed as a UNESCO World Heritage property.

Significant characteristics include clustered panels of engravings on schist and granite surfaces positioned along riverbanks and cliffs, with stylistic elements attributed to Upper Paleolithic artists as well as to later prehistoric communities. The sites are among the most important examples of Palaeolithic open-air art in Europe.

Archaeological study and conservation efforts since the late 20th century established the antiquity and cultural importance of the engravings and led to the protection and management of the sites. Public access is managed at visitor centres and designated viewing points to protect the rock art.

The Côa Valley sites lie along the Côa River in Guarda District, Portugal, while the Siega Verde panels are located across the border in the province of Salamanca, Spain; they occupy river valleys with steep banks and are accessed via regional roads and dedicated viewpoints.

  • Scale and age: The ensemble comprises thousands of engravings created over millennia, with motifs dating from the Upper Paleolithic into later prehistoric periods.

Tips for Visiting Prehistoric Rock Art Sites in the Côa Valley and Siega Verde #

  • Book a guided visit through the Museu do Côa or the official visitor centres before you go - many valley panels are only viewable on supervised tours to protect the engravings.
  • Start early in the day for softer light on the engravings and to secure smaller-group slots; the valley viewing platforms and riverfront trails are noticeably quieter at first light.
  • Don't skip the museum and interpretive centres: they provide essential context and reproductions so you appreciate the scale and techniques of the open-air rock engravings that are easy to overlook in situ.
