Alongside the church itself, many Irish devotional traditions have continued for centuries as a part of the church's local culture. One such tradition, unbroken since ancient times, is of annual pilgrimages to sacred Celtic Christian places such as St Patrick's Purgatory and Croagh Patrick. Particular emphasis on mortification and offerings of sacrifices and prayers for the 'Holy Souls' of Purgatory is another strong, long time cultural practice. The Leonine Prayers were said at the end of Low Mass for the deceased of the penal times. Patterns (processions) in honour of local saints also continue to this day. Marian Devotion is an element, focused on the shrine at Knock, an approved apparition of the Virgin Mary who appeared in 1879. Feasts and devotions such as the Immaculate Conception of Mary (1854) and the Sacred Heart of Jesus (1642), and the concepts of martyrology are very prominent elements. Respect for mortification of the flesh has led on to the veneration of Matt Talbot and Padre Pio.
