Muralla de Finestres (the Wall of Finestres). The doubled walled cliffs have a beautiful hermitage in the middle with a spectacular view of the reservoir.
The name Finestres is based on the nearby abandoned town of Finestres.
In 1960, due to the construction of the dam across the Noguera Ribagorçana river, the farmland in the region was flooded.
The abandoned village still stands.
