Sierra de las Moreras

Sierra de las Moreras is a mountain range on the western edge of the municipality of Mazarrón, in the Region of Murcia, southeastern Spain. It rises above the Mazarrón basin, a horseshoe-shaped valley open to the north and sloping gently south toward the Mediterranean coast. The range sits at approximately 37.58468, -1.39989.

What is Sierra de las Moreras?

It is a modest, dry mountain range typical of Spain's southeastern Mediterranean coastline — rocky, sparsely vegetated, with a gentle yet clearly defined profile. The sierra acts as a natural boundary separating the Mazarrón valley from the surrounding land, and its slopes have been a site of human settlement and mining activity for centuries.

What historical significance does the area hold?

At the foot of Sierra de las Moreras lies one of the region's most important archaeological sites, Cabezo del Plomo, a Chalcolithic (Eneolithic) settlement dated to the fourth and third millennia BC. This shows the land was inhabited and used by people for thousands of years, long before the mining industry that would later make Mazarrón famous.

How is the sierra connected to Mazarrón's mining history?

The Mazarrón area, whose western fringe includes Sierra de las Moreras, holds one of the oldest and most significant mining histories on the Mediterranean coast. Exploitation of lead, zinc and silver deposits began as early as the 2nd century BC, during the expansion of the Roman Empire, when Mazarrón grew in importance precisely because of the mineral wealth of its surrounding hills. Mining in the region continued for centuries, but it was the 19th century, with the arrival of the Industrial Revolution, that brought a true boom in extraction, reaching its peak at the turn of the 19th and 20th centuries. While the mining works themselves are concentrated mainly in other parts of the Mazarrón basin, the sierra forms the geographic and geological backbone of that story, shaping the landscape in which the region's entire mining activity developed.

What should visitors know before coming?

Sierra de las Moreras appeals to those interested in the dry, mountainous hinterland typical of the Murcia coast, as well as in the region's history — both its earliest layers, reaching back to the Chalcolithic period, and its centuries-long mining tradition around Mazarrón. From its slopes, views open out over the Mazarrón basin and toward the Mediterranean coastline.
