Ojo Guareña, Cave complex in Merindad de Sotoscueva, Spain
The Ojo Guareña system extends through 110 kilometers of underground galleries across different levels within a limestone and dolomite geological formation.
The first speleological exploration occurred in 1956 by the Edelweiss Group, leading to discoveries of artifacts from various civilizations throughout Iberian Peninsula history.
The Cave of San Bernabé contains remarkable murals from 1705 and 1877 depicting Saint Tirso's life, along with ancient rock engravings and paintings.
The cave system maintains temperatures between 7 and 9 degrees Celsius, requiring visitors to wear appropriate clothing and reserve tickets before their visit.
Scientists have identified 190 animal species within the caves, including 16 endemic invertebrates and multiple species previously unknown to science.
