Tethys

Tethys was an ocean between ancient continents of Gondwana and Laurasia during the Mesozoic Era. The 150 million year-old limestone, which was then the seabed of Tethys, was lifted during Tertiary Era. And over the years through erosion, the Karstic landscape of today's El Torcal was formed.
