In the maturity of the life, when Gaudí had made the sixty-three years, in 1916, he received the two hundred and fifty internal pupils of the Piarists Fathers School of Sarrià in the works of the Holy Family. Gaudí reminded of his first studies the School Pie of Reus and the devotion that the "small office" of Virgin, who they prayed every Saturday, had awakened him for the liturgical knowledge that a day he should apply as an architect of the Temple. "At School Pie -he said-, it passed my first years, and my first prayers would be there the psalms and verses contained in the little prayer book, book of gold of my liturgical interests; and in its classrooms I learned the fear saint of God, for which I never forget so beautiful religious institution, admiration of the centuries and the one that has more friendliness”. In being finished the visit, they went down to the Crypt, open to the cult. After the blessing with the Holy Sacrament, made the reservation, Gaudí, as his teenage years, joined his voice to those of the other schoolboys to sing the Gregorian Salve.
