Mina de São Domingos
Mértola, Portugal
An abandoned copper mine with coloured acid pools, ruined works and a flooded pit, next to a village of miners’ cottages. A river beach nearby is popular for swimming in summer.
The São Domingos Mine lies about 17 km east of Mértola on the N265. The Romans were already extracting ore here; their pit was an open-cast mine around 40 m deep. From 1858/59 a British company worked the mine until it closed in 1966, at first mainly for copper and later also for pyrite. The British built an entire village with housing for the workers, a theatre, a church and sports facilities. The site is abandoned; the open pit, many old buildings and pools of acidic, blood-red waste water still characterise it today.
The trackbed of the former railway runs to the river port of Pomarão on the Guadiana. At the Tapada Grande reservoir there is a river beach with a leisure area. The village feels almost deserted today. In high summer it is best to avoid the midday heat on the shadeless site.
