Cabrera Range

The Sierra de la Cabrera forms part of the rugged mountain country south of El Bierzo. Ancient glaciers shaped its upper valleys, and streams descending from the range were later tapped by Roman engineers. Channels carried water across the slopes toward the vast gold workings of Las Médulas, where hydraulic mining cut into the deposits above the Sil valley. The remains of these channels reveal the scale of the ancient enterprise among the mountains.
