The Monasterio de Piedra is in a mountainous region, at around 736 m above sea level in the Iberian System. The traditional access road to the monastery follows the Piedra River, starting from the Nuevalos village. Along the old path are the masonry ruins of a watermill or wheel. This beautiful spot is often used by the Cistercians as inspiration for their work and prayer. The Monasterio de Piedra was founded by Alfonso II in 1194 with monks from Poblet. The work started in 1195 and was completed in 1219.
