Knock ("An Cnoc" in Irish, meaning "The Hill" – but now more generally known in Irish as "Cnoc Mhuire", "Hill of (the Virgin) Mary") is a small town in east County Mayo in Ireland. Knock's notability comes from the Knock Shrine Apparition of 1879. At 8:00PM on 21 August 1879, it was reported that the Virgin Mary, together with St Joseph and St John the Evangelist, appeared to local people.
