El Bierzo is a comarca in the province of León, Spain. Its capital is the town of Ponferrada. Other major towns are Bembibre and Villafranca del Bierzo, the historical capital.
The territory of El Bierzo includes most of the upper basin of the Sil river. It is surrounded by mountains on all sides, which makes this area remarkably isolated from all neighbouring lands.
