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 historic Portuguese border village located in the district of Beja, in the Baixo Alentejo sub-region. Popularly known as a "Museum Village", the settlement rises strategically on a rocky outcrop at the confluence of the Oeiras stream with the Guadiana River. As this is the last navigable post of the river, the village has played a crucial commercial and military role for various civilizations over the centuries.👍🥾🚲

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.

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.
