GALERIE FOTO: În 2008, Spania a umplut o mină de cărbune adâncă de 300 de metri cu 547 miliarde litri de apă. Patru ani mai târziu, „groapa” s-a transformat într-un lac artificial care acoperă 865 de hectare

In northwestern Spain, a former coal mine has been transformed into a large artificial lake, covering 865 hectares. This project, initiated in 2008, involved filling a deep pit with 547 billion liters of water, creating one of Spain's largest artificial lakes. The mine, operational since the 1940s, was closed in 2022 due to environmental regulations. The lake now attracts tourists for activities like kayaking, contributing to the local economy. As Pontes serves as a model for ecological recovery, showcasing how former mining sites can be repurposed for tourism and environmental restoration.
