Cave of La Pasiega

The Cave of La Pasiega in Puente Viesgo, Cantabria, was discovered in 1911 by Hugo Obermaier and Paul Wernert. Spanning approximately 400 metres with four main galleries, it contains more than 700 images including paintings, engravings, and petroglyphs. About 40% depict animals such as deer, horses, ibex, and bison, while the rest are abstract symbols including tectiforms and a notable ladder-shaped sign dated to around 64,000 years ago, attributed to Neanderthals. A UNESCO World Heritage Site since 2008 as part of the Cave of Altamira and Paleolithic Cave Art of Northern Spain, the cave remains permanently closed to preserve its art.
