A Treasure Trove of Diverse Minerals
Almería's mineral wealth extends far beyond common knowledge. A deeper look reveals a diverse and strategically valuable treasure trove. While copper and silver are well-known, the region boasts a variety of other precious resources.
The Gleaming White Marble of Macael
Since Roman times, the gleaming white marble of Macael has been prized for its beauty and quality. This iconic stone has adorned countless structures and sculptures throughout the world.
Veins of Lead and Silver in the Sierras
The Sierra Gádor conceals rich veins of lead, while the Sierra Almagrera boasts significant deposits of silver. These mineral-rich mountains have played a crucial role in Almería's economic history.
The Gypsum Wonders of Sorbas and Pulpi
Pulpi Geode
Near Sorbas, extensive gypsum deposits hold immense potential. But perhaps the most spectacular gypsum formation is found in Pulpi. Here, at the southern end of the Sierra de Las Moreras, lies Europe's largest gypsum geode, a cavern glittering with colossal crystals.
The Crystal Giant: Europe's Largest Gypsum Geode
The geode in Pulpi is a true marvel, one of the geological wonders of Almería. Its sheer size and the breathtaking beauty of its crystals make it a must-see for any visitor.
Iron and Gold: From Sierra Alhamilla to Cabo de Gata
The impressive iron deposits, stretching from the Sierra Alhamilla to the northern flanks of the Sierra de Los Filabres, and the gold found at Rodalquilar in Cabo de Gata, further highlight the region's mineral diversity.
Overcoming the Challenges of Transportation

Exploiting these resources required the development of an extensive transportation infrastructure. Connecting the mines to coastal ports like Almería, Agua Amarga, Carboneras, Garrucha, Villaricos, and Águilas was a monumental task.
19th-Century Challenges: Rough Roads and Rugged Terrain
Until the mid-20th century, the road network consisted of unsurfaced roads and donkey trails. The challenging terrain, with its steep valleys and unpredictable flash floods, made transportation difficult.
The Rise of the Railways: Connecting Mines to Ports
Undeterred by these challenges, companies like the Great Southern of Spain Railway Company and the Alhamilla and Almería Railway Co. Ltd. built railway lines to transport ore. These lines, along with iconic structures like El Cable Inglés, revolutionized the region's mining industry.
The Ingenuity of Louis Siret
Louis Siret, an archaeologist and mining engineer, demonstrated remarkable ingenuity by constructing a 60 cm railway line in just 40 days. His innovative track design and use of donkey trucks highlight the resourcefulness of the era.
Almería's Industrial Heritage

I often use AI such as Gemini, to generate the source of materials for my articles. I then sift through those sources to find the most reliable; books, academic or research papers, reputable websites and so on. AI again comes in useful, specifically NotebookLM, in analysing the content of papers.
I then write my article. My aim is to give new insights, or look at a subject from a different angle, to further our understanding of that period or event in history. AI again comes into its own when I use it to see if my ideas or angle are novel. I then use AI to fact check, AI, like humans, can still get it wrong.
