Nestled in the lush, green landscapes of northwestern Spain, Lake As Pontes (Lago de As Pontes in Spanish, Lago das Pontes in Galician) is one of Europe’s most notable examples of ecological restoration. Once a large open-pit lignite coal mine located in the municipality of As Pontes de García Rodríguez, Galicia, it has been transformed into Spain’s largest artificial lake—a magnificent 865-hectare body of freshwater that represents a transition from industrial activity to environmental renewal.

From Open-Pit Coal Mine to Artificial Lake
For more than three decades, from 1976 to 2007, the site was operated by the energy company Endesa, extracting over 260 million tonnes of lignite to power the local thermal power plant. The mining operation created a massive crater approximately 5 kilometres long, reaching depths of up to 300 metres.
The History of the As Pontes Coal Mine
Once mining activities stopped in 2007, local authorities and environmental engineers launched a major effort to flood the site. Over four years, from 2008 to 2012, rainfall, water diverted from the nearby Eume River, and local runoff slowly filled the huge void, forming a reservoir capable of holding well over 540 million cubic metres of water.
