The History of Kieran Gatehouse:

The Kieran Gatehouse (circa 1865), had served as the gatehouse to the Rosenlund Estate purchased by the Marist Brothers in 1908. This quaint cottage has remained in constant use, first as a residence for some teaching and working brothers and then as headquarters for the Poughkeepsie Province of the Marist Brothers, a faculty residence and subsequently as office space and a private home.

In October 1990, it was dedicated to the memory of Brother Kieran Thomas Brennan who had been the director of student brothers from 1957-1964. A founder and longtime trustee of Marist College (1959- 1974), he was then named a Life Trustee. Brother Brennan died on September 5, 1989.

Brother Paul Ambrose Fontaine, the first President of Marist College (1946-1958) lived at Kieran from 1989 to 2000.
