The Apparition at Knock is the third edition of this book by Monsignor Michael Walsh, first published in 1955. A native of the area, Monsignor Walsh has revised and annotated this immensely edifying and important document on the apparition of the Blessed Virgin Mary on 21 August 1879. The huge numbers of people still visiting Knock today bears testament to the historical relevance of the Shrine for the prayer-life of men and women in Ireland and all over the world. It is not only informative and inspirational but also deeply nourishing and spiritual.
