Holy Ghost Missionary College, Kimmage Manor, Dublin

Kimmage manor was bought by the Spiritans (under Provincial Fr. John Tuohill Murphy and former president of Pittsburgh Catholic College, later renamed Duquesne University), in 1911, initially as a novitiate where students pursued philosophy studies with the National University of Ireland (UCD). It developed into a seminary where students, studied theology and philosophy at Kimmage, while also took civil degrees in University College Dublin. In 1917 the Faculty of Theology for Irish Holy Ghost Fathers, which had been based in Chevilly, near Paris, opened in Kimmage Manor with 29 students. From 1924 until 1933 the Holy Ghost Fathers studied theology at Blackrock Castle, before returning to Kimmage Manor. In 1917 the House of Philosophy moved to St Mary's College, Rathmines, Dublin, then in 1926 it moved to Blackrock College, before moving back to Kimmage in 1938.[3] Kilshane House, County Tipperary, operated as a junior novitiate from 1933 to 1983,[4] with students moving to Kimmage to complete their studies. In 1939 the Kimmage Manor Church was opened on the college campus. In 1959 the Mission House opened which would serve as a retirement home and accommodation for those returning from mission. During the tenure of Kimmage alumnus Archbishop McQuaid, he would have conducted ordinations of priests trained from Kimmage, in Clonliffe College Chapel. During his tenure as superior of the order Archbishop Marcel Lefebvre who would later lead a schism from Rome, ordained spiritan priests in Kimmage.

The Mission House opened in Kimmage in 1959.[5]

1974 under Rev. Dr. Liam Carey, the adult education dept was set up this would evolve from 1977 under Fr. Richard (Dick) F. Quinn C.S.Sp., into the Development Studies Centre. In the 1970s students from other orders (e.g. Redemptorists from Marianella) and lay people began to be trained in Kimmage, also in the 1980s students of the Bachelor of Divinity course were allowed to sit for degrees from the Pontifical University Maynooth. In 1979 Kimmage became one of the five private providers recognised by the Irish Government's HETAC forerunner the National Council for Education Awards (NCEA), providing accreditation for some of its certificate and diploma courses.[6] In 1990 the college church becomes the Kimmage Manor Parish Church.

The Congregation of the Holy Spirit Graveyard, which was on the campus, is now separated from Kimmage Manor following land sales, and development, it is located at Wainsfort Manor Grove. The spiritans new graveyard is located in Dardistown.

The Development Studies Centre, was founded in 1974, as part of the Faculty of Theology, and operated until 2018 when it was merged into Maynooth University as its Development Studies Department.[7] The development studies programme grew out of the fourth-year pastoral theology course at Kimmage, which seminarians took.

The Kimmage Mission Institute of Theology and Cultures (KNI), was founded in Kimmage in 1991 (in association with other Irish missionary congregations), the Institute moved to Milltown Institute of Theology and Philosophy in 2003, formally merged with Milltown in 2006.
