The English Mission has traditionally worshiped in the smaller Crypt Chapel dedicated to St. John the Baptist which is also called the Advent Chapel to commemorate the Church of the Advent which the Cathedral replaced. The Rt. Reverend Mark Trollope is buried in the Crypt Chapel and his remains lie under a copperplate engraving of him by Francis Cooper which was completed in 1932. At present up to one hundred worshipers, foreigners and Koreans, gather in the Crypt Chapel for Holy Communion in English every Sunday at 9.30 am. At other times the Chapel is used for Korean Language Worship. As from the very beginnings of the English Mission the congregation is drawn from many different countries and is united by a desire to worship in the Anglican-Episcopal usage in the English language. The growth in numbers and nationalities attending services at the English Mission in the period from the mid-1990s onwards reflects the growth of Seoul as an East Asian mega city with over 180,000 foreign dwellers recorded in 2007.
