‘Missionsbenediktiner van St. Ottilien’ is the first male convent in Korea. Its history is distinguished in three steps as Seoul period(1909-1927), Duckwon-Yanji Period(1927-1946), and Waegwan Period(1952-). In this study, I have investigated the Location, Arrangement and Architectural style of Pek Dong Abbey, the old Deokwon abbey, and Waegwan Abbey. Each abbey was reflected in the pastoral, social and economic background at the time. Among them Duckwon abbey can be evaluated as the best ideal abbey which presents the combined model of monasteries and missions.
