What was discovered

A prehistoric cave in Cantabria (Spain), declared a World Heritage Site as part of the Altamira and Palaeolithic Cave Art of Northern Spain group; in 1907 Hermilio Alcalde del Río discovered Magdalenian engravings inside it depicting a bird and a possible horse.

Wikidata attributes the find to Marcelino Sanz de Sautuola in 1878, but the article itself dates the discovery of the engravings to 1907 by Hermilio Alcalde del Río; this more detailed version is followed here.

What it led to

  • Systematic archaeological excavations revealing a highly significant stratigraphy
  • Inclusion in the Altamira World Heritage group (2008)
  • Expansion of the catalogue of Cantabrian Palaeolithic cave art
