Cabezo Gordo

Cabezo Gordo is a solitary hill rising out of the flat Campo de Cartagena plain in the Murcia region, within the municipality of Torre Pacheco. Reaching 312 metres above sea level and stretching roughly 3 kilometres in length, it is the only natural elevation in the entire municipality. Beneath its unassuming surface lies one of Europe's most significant paleontological sites, alongside centuries of mining history.

How did this hill form?

Geologically, Cabezo Gordo belongs to the Nevado-Filábride complex, whose rocks date back to the Triassic period. The uplift of the massif came much later, during the Alpine orogeny, triggered by the collision of the African and Eurasian tectonic plates. This process produced low-grade metamorphic marbles that make up the hill's core — a resource that has drawn people to the site for millennia.

Why did miners take an interest in this place?

The marble deposits of Cabezo Gordo were already being quarried in Roman times, and extraction continued for centuries afterward. In the late 19th century, the massif also attracted prospectors searching for magnetite, who carved vertical shafts and galleries into the rock. Once mining activity ceased, some of the abandoned workings found a new purpose: in the 1970s, the naturally humid tunnels were repurposed for growing mushrooms, a practical way of making use of the leftover industrial infrastructure.

What was discovered at Sima de las Palomas?

Cabezo Gordo owes much of its fame to a discovery made in 1991. Inside a cave known as Sima de las Palomas, researchers uncovered Neanderthal remains of major scientific importance for the study of this human species in Europe. The site is considered the second most important Neanderthal location in Spain, surpassed only by the renowned Atapuerca complex. The paleontological and archaeological findings from this cave remain the subject of ongoing scientific research, offering insight into life and environmental conditions tens of thousands of years ago.

What protection status does Cabezo Gordo hold today?

Given its outstanding natural, scenic, cultural, and paleontological value, the area was granted protected status in 1998 under the Natural Resource Management Plan for the open spaces and islands of the Mar Menor and Cabezo Gordo. The hill was designated a Protected Landscape (Paisaje Protegido), a measure intended to prevent further degradation of the site and preserve its unique features for both scientific study and future generations of local residents.

Frequently asked questions

Can Cabezo Gordo be visited? Yes, the area is open to visitors as a protected landscape, although some of the old mining excavations and the paleontological site require particular care due to their scientific value.

Why is this site important to scientists? Because of the Neanderthal remains discovered at Sima de las Palomas, which offer valuable insight into the life of this human species in Europe and rank among the continent's key sites of this kind.

What sets Cabezo Gordo apart from the surrounding landscape? It is the only natural elevation in the entire municipality of Torre Pacheco, rising clearly above the flat Campo de Cartagena plain and serving as an easily recognisable landmark in the region.
