St Mary's College is a boys secondary school in Galway, Ireland. It educates students aged 12 to 18 for the Junior and Leaving Certificate examinations. It was founded in 1912 as the junior seminary of the Roman Catholic Galway and Kilmacduagh dioceses. It teaches boys to the Junior Certificate and Leaving Certificate examinations. St. Mary's College retains the status of diocesan college although it recently ended its boarding provision (1999). The school will celebrate its centennial in 2012, celebrating the completion of its main building in March 1912. The building is faced with granite and limestone, the two predominant stones of County Galway's geology. Former students include former Fianna Fáil government minister Frank Fahey, the actor Mick Lally and deceased Bishop of Galway, James McLoughlin. Junior boarders, especially first years, lived in fear of the annual appearance of the Red Hand. Junior Dormitory was in the old college chapel which was held to be haunted by a questing severed hand. There were different stories of the origin of this story, each more macabre and embellished.
