The ruins of the Minas de São Domingos, located in the municipality of Mértola, Alentejo, constitute one of the most impressive and enigmatic abandoned industrial settings on the Iberian Peninsula. With origins dating back to Roman times, the complex experienced its peak under British management by the company Mason & Barry from 1854 onwards, becoming a true industrial enclave focused on the massive extraction of copper pyrite and sulfur until its closure in 1966. The abandonment gave way to an almost apocalyptic landscape, where reddish soils, acidic waters, and old degraded masonry structures attract photographers, the curious, and industrial tourism enthusiasts.👍🥾🚲

Mértola is a beautiful Alentejo village, bathed by the Guadiana River. It has a walking trail that I did and really enjoyed. 👍🥾

A beautiful spot from which you can anticipate the crossing from Portugal to Spain, crossing under the Chanza reservoir dam, next to the Guadiana River.

On the south bank of the Guadiana, before crossing into the city, you have a beautiful view of Mértola, especially with its castle at the top of the hill and the rest of the city spread out over the hill.

Along the Ribeira do Geraldo, the Tapada Grande Dam Reservoir holds an unexpected treasure: this serene river beach, with golden sands, fresh lawns, and every comfort for leisure. Once a vital reservoir for the old mining industry, today it is a setting for rest and harmony. Nearby stands the town of Minas de São Domingos, born of the mining past and still marked by the memory of this unique heritage.

The São Domingos Mine is a living memory of a time of fire and iron. Here, where the earth opened up to reveal gold, silver, and copper since ancient times, one of the greatest legacies of the Iberian Pyrite Belt arose in the 19th century. Between 1854 and 1966, millions of tons of ore were extracted here, leaving not only its mark on the soil and landscape, but also progress: one of the country's first railway lines and the first power plant in the Alentejo. Today, the former mining complex is a public heritage site, a place of contrasts and rare beauty.

The old, abandoned copper mines resemble a lunar landscape: a strange and fascinating stage, illuminated by the reflections of copper-hued lakes. A road cuts through the landscape, guiding you along dirt roads. Streams and wells glow in unlikely colors, from copper to green to deep black. Signs warn of the dangers of the water, but nothing prevents your gaze from losing itself in the dramatic and unsettling beauty of the place.
