In 1900, a more hospitable atmosphere between Russia and Korea allowed a second missionary team led by Archimandrite Chrysanthos Shehtkofsky to begin an outreach in Seoul.

The first Orthodox church was constructed in Jung Dong, Jung-gu, the central area of Seoul in 1903 and was consecrated in honor of Saint Nicholas (the building has not survived).

In 1953, Army Chaplain Archimandrite Andreas Halkiopoulos of the Military Forces of Greece was made aware of Korean Orthodox faithful and arranged for a parish in Seoul to be reestablished.

On 25 December 1955, after the Christmas Divine Liturgy, the General Assembly of the Orthodox Community of Saint Nicholas in Seoul unanimously decided to request being received in the jurisdictional authority of the Ecumenical Patriarchate of Constantinople.

It also has the Missionary Center, the Publishing House under the name of "Korean Orthodox Editions", with publications in Korean, two bookstores (Book Café “Philokalia” in Seoul and the Book Café “Logos” in Incheon), the Camp in Chuncheon, a kindergarten under the name of “Annunciation” in Busan, the Centre of Social Welfare for the Elderly in Chuncheon, the Orthodox cemetery in Yeong-miri.

[2] Additionally, in the early 2000s the government of North Korea established the Korean Orthodox Committee and began the construction of a church building in the capital Pyongyang.

[10] The parish remains effectively under the jurisdiction of the Moscow Patriarchate, which in February 2019, following the Moscow Patriarchate′s unilateral severance of communion with the Patriarchate of Constantinople, established its own diocese of Korea (claiming both North and South), a move publicly condemned by Metropolitan Ambrosios of Korea,[1] but defended in a response by Metropolitan Sergius (Chasin) of Singapore and Southeast Asia.
