Traffic-free bike rides around Mértola
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.👍🥾🚲

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.

The castle sits atop a hill overlooking the Guadiana River. The river forms the natural border between Portugal and Spain.

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.
