St. Kevin’s, Glenart, Arklow, Co.Wicklow was purchased in the late 1940s to provide student accommodation for the Vincentian student body, due to increasing numbers. The theology students were moved to Glenart, the philosophers/university students and seminarists remaining at Blackrock. The move was made in 1949. Glenart continued to serve as a theology house until 1968, when they moved back to Blackrock. From then until 1978 it served as a Retreat House, and was much used by the Irish Missionary Union for courses for returning missionaries. In that year it was sold. A field was retained which was not sold until 1996.
