St Joseph's Industrial School was an industrial school for young boys in Letterfrack, County Galway, Ireland. The school was built in 1886/7 after the designs of the architect William Hague, opened in 1887, and run by the Congregation of Christian Brothers. St Joseph's received a lasting notoriety through revelation of physical and sexual abuse of the boys by some of the Brothers there, with evidence of sexual abuse and extreme physical punishments going back to the 1930s. 147 children died there while in the care of the Christian Brothers mainly from abuse and neglect.
