Ji Yoon-su (Im Soo-jung) brings Baek Seung-yoo (Lee Do-hyun) to this location (seen as ‘Salesio Sanitorium) in episode 3 of Melancholia (멜랑꼴리아) (tvN, 2021). Here, he gets acquainted with former math professor Ji Hyun-wook (Oh Gwang-rok), who is also Yoon-su’s father. They both return here separately in episode 6. Note that the bus stops along the main road does not exist in real life, and that the street leading to the church is longer than the drama makes it out to be.
Angel Kim Dan (Kim Myung-soo/L of Infinite) gets the orders from his superior at this church; including his new human form in Angel’s Last Mission: Love/Dan, Only Love (단, 하나의 사랑) (KBS2, 2019). The church is first seen in episode 2, when Kim Dan doesn’t make it in time to the deadline given to him by his senior.
Also seen in episode 9 of The King: Eternal Monarch (더킹:영원의 군주) (SBS, 2020).
Hapdeok Catholic Church [합덕성당 or 천주교 합덕성당], built in 1929, is a catholic church located in the village of Hapdeok [Hapdeok-ri/합덕리] in Dangjin’s Hapdeok Township [Hapdeok-eup/합덕읍], about 2 hours south of Seoul by public transport.
This Gothic-styled church, which has twin bell towers, particularly stands out in terms of architecture as it was built from a rather unconventional wood and brick mix.
