Mina de São Domingos
Beja
São Domingos Mine is a deserted open-pit mine located in Corte do Pinto, in the municipality of Mértola, Alentejo region, Portugal. It is part of the Iberian Pyrite Belt, a major volcanogenic massive sulfide ore deposit extending from southern Portugal into Spain. Mining activities began in the Bronze Age and intensified under Roman rule, focusing on gold and silver extraction. The mine was revived in the mid-19th century by international companies, notably the English firm Mason and Barry, which transitioned operations to open-pit mining. Copper was the primary product initially, but by the end of World War I, pyrite mining for sulfuric acid production became dominant. This shift led to severe environmental contamination due to sulfuric acid leaching and toxic fumes affecting miners' health. The mine ceased operations in 1966 amid growing environmental concerns and regulatory pressures. Today, the site is a tourist attraction featuring remnants of mining infrastructure, a museum depicting miners' lives, and the converted mining company headquarters serving as a hotel. The area also includes an English cemetery reflecting the presence of Cornish mine managers and workers. São Domingos Mine holds cultural and historical significance as a major mining center that shaped the region's development and industrial heritage.
ヒント: Visitors should plan their visit during mild weather seasons to fully explore the open-pit mine and museum facilities. Booking accommodations in advance is recommended due to limited lodging options in the area. While the railway is no longer operational, walking the old trackbed offers insight into the mine's transport history. Discounts may be available for groups or educational visits. Guided tours provide valuable context and are advisable for a comprehensive experience.

The mine shifted from tunnel to open-pit mining in 1867 to meet industrial demands.
The focus moved from copper to pyrite for sulfuric acid production after World War I, causing environmental damage and health issues.
The mine closed in 1966 due to environmental legislation and economic pressures, marking the end of an era for the region's mining industry.
