Tradition tells that in 1688, two pilgrims, Juan Bautista and Manuel Terrín, stayed at a local farmhouse and, in gratitude, painted an image of the crucified Christ using colors mixed with saliva. When he asked for oil to light the image, the owner miraculously found enough oil to last 24 hours, despite claiming to have none. This event was considered miraculous and prompted the construction of the hermitage at the initiative of Francisco Rodríguez Palmero, who donated the land to the Order of Saint John.
