Roman Catholic Archdiocese of Seoul

The Roman Catholic Archdiocese of Seoul (Latin: "Archidioecesis Seulensis", ) is a Metropolitan archdiocese of the Latin Rite of the Roman Catholic Church comprising the metropolitan area of Seoul, South Korea, whose province comprises parts of South Korea (which has two more provinces) and all North Korea, yet depends on the missionary Roman Congregation for the Evangelization of Peoples.
Its Metropolitan bishop as the "Archbishop of Seoul" resides at his Myeongdong Cathedral in Jung-gu, Seoul. The Archbishop of Seoul is also the Apostolic Administrator of the Diocese of Pyongyang in North Korea. As the episcopal see is the oldest one in Korea and that of its capital city, he is often considered to be so called the "Primate of Korea", though the official title has not been expressly granted by the Holy See by canonical decree.
There are 57 Catholic secretly active parishes in North Korea, but due to the current regime in place, no Catholic priests are permitted permanent residency at current time.
