This mystical cave is located in Manresa, 66 km away from Barcelona, and very close to the Montserrat mountain and Monastery. It is a very special place overlooking Montserrat mountain, where Ignatius de Loyola retreated for a 11 months in penitence to pray and write in 1522. He was fascinated by its beauty, its location by the Cardener river, and the kindness of its inhabitants who took care of the poor pilgrim who had walked down Montserrat wearing sandals. Here St Ignatius de Loyola took notes for the «Spiritual Exercises», the founding text of the Jesuit religious order founded in 1540.
