The construction of the chapel of Blessed John of Spain is linked to the history of the Carthusian monastery (now the Carmelite monastery) and the village of Le Reposoir.
The Carthusians built a chapel in 1891 on the foundations of the church of the first 12th-century monastery. However, Jean d’Espagne had decided to move the community from its original site (located at the entrance to the former Béol Valley, the former name of the Reposoir Valley) and settle it one kilometer away, on a plateau, where the Chartreuse stands today, as the original site was too small and threatened by flooding from the Foron River. It was at the end of the 19th century that the Carthusian Fathers uncovered the foundations of the original sanctuary. Two architects identified it as 12th-century Romanesque in style. It was in this same style that the Carthusians built the current chapel, in honor of the founder of the Chartreuse: Blessed John of Spain.
Every year on June 25, the anniversary of the death of Blessed John of Spain, the parishioners of Le Reposoir make a pilgrimage to this chapel, built in honor of the monk.
