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.👍🥾🚲

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.👍🥾🚲

High on a hill near Afonso Vicente, stand the Lavajo Menhirs, Neolithic stone sentinels that have guarded the silence of this valley for over five thousand years. Carved in greywacke and engraved with circles and dimples, these monoliths seem to align themselves in an ancient mystery. Recovered and restored in 2004, they have returned to their original location, inviting passersby to imagine a time when the stone spoke to the sun.

Along the Guadiana, the path meanders serenely, following the river's slow rhythm between hills of olive, almond, and fig trees. A former river of fishermen and miners, the Guadiana, called the "river of ducks" by the Romans, continues to connect Alentejo with Algarve and Portugal with Spain, a tranquil mirror of southern history and life.
