Myeongdong Cathedral, Roman Catholic cathedral in Myeong-dong, Seoul, South Korea

Myeongdong Cathedral is a Gothic Revival Roman Catholic cathedral in Myeong-dong, Seoul. Its facade is built of reddish-brown brick with light grey stone trim and has a single tall square bell tower on the left, topped by a steep dark green spire with corner pinnacles. Below the spire are narrow paired arched openings and a round white clock face; the main body extends to the right with a steep green roof and tall pointed-arch windows, rising above a terraced slope with low brick walls.

The cathedral was completed in 1898 and became the first Gothic-style parish church on the Korean Peninsula after missionaries from France acquired the site. During the democracy movement of the 1970s and 1980s, church representatives opened the building to activists and offered protection from government intervention.

The building takes its name from the surrounding neighborhood and acts as the seat of the Archbishop of Seoul, marking its position within the country's Catholic life. On Sundays, worshippers from different nations gather here, and the plaza outside becomes a space where people meet and talk after services.

The cathedral stands near exits 5 and 6 of Myeongdong subway station and opens daily from 6 AM to 7 PM for visitors and worshippers. Those wishing to see the interior should be mindful of ongoing services, as silence is expected during these times and photography may be restricted.

The site on Jonghyeon, or "Bell Hill", had been avoided by Koreans because of its proximity to a Confucian temple, which is why the missionaries could buy the vacant lot. The name Jonghyeon recalls a Ming general who is said to have camped here during the Imjin War and had the bell from Namdaemun brought up.
