La Garma cave complex, Cave complex with Paleolithic art in Ribamontán al Monte, Spain

La Garma is a karst cave system on the southern side of La Garma Hill, north of Omoño in Ribamontán al Monte, Cantabria. Its ten archaeological sites include La Garma A, the only current entrance, La Garma B, and the Lower Gallery, a 300 m passage at 59 m above sea level. The Lower Gallery holds a Magdalenian floor of over 500 m² with thousands of animal bones, shells, stone tools and three stone structures.

The cave was occupied by humans over thousands of years, as shown by finds on multiple levels. Around 15,000 years ago, a landslide sealed the lower section and preserved everything inside in its original state.

Hand prints and animal drawings on the walls show how early people left their marks in this space. These traces reveal the lives of humans who inhabited this region thousands of years ago.

The only entrance to the system runs through La Garma A, at 80 m above sea level, and the Lower Gallery lies at 59 m, reached after passing La Garma B and the Intermediate Gallery. The sealed floor keeps access restricted to researchers, so visitors plan around the site's documentation rather than a walk-through.

A prehistoric landslide sealed a lower gallery and created one of the world's largest undisturbed Paleolithic floors. Objects in this sealed chamber remain exactly where early people left them thousands of years ago.
