In the news, we see Reporter Bong Doo-Hyun (Oh Eui-Sik) in front of this prison, explaining that an inmate has killed himself leaving a note that he was framed in episode 24 of While You Were Sleeping (2017) (당신이 잠든 사이에) (SBS, 2017).
This is the prison Han Sung-Joon (Lee Tae-Hwan) stays in in Father I’ll Take Care of You (2016-17) during episode 47 and 48.
In a flashback in episode 5 of The Man Living in Our House/Man Living at My House/Sweet Stranger and Me (우리집에 사는 남자) (KBS2, 2016), we see that Go Nan-Gil (Kim Young-Kwang) was in prison here.
In Jang Bori Is Here (2014), Kang Nae-Cheon (Choi Dae-Chul) was locked up here.
Seodaemun Prison History Hall [서대문형무소역사관] was a real prison, built end of the Joseon Dynasty (around 1910), in which independence activists were jailed. Now it serves as a museum. Especially in older K-Dramas this museum figures as a prison. This was probably before the Iksan Prison Set existed. It’s also more seen in weekend K-Dramas.
This building is located in Hyeonjeo-dong [현저동], Seoul.
