The police cracks down a cellphone dealer and his victim here in episode 25 of While You Were Sleeping (2017) (당신이 잠든 사이에) (SBS, 2017). As the story tells us, the dealer is the brother of the murderer of Nam Hong-Joo’s (Bae Suzy)’s and Jung Jae-Chan’s (Lee Jong-Suk) dads.
Bong Pil (Kim Jae-Joong) runs through this tunnel to finally confess his love to Kang Soo-Jin (Uee) in episode 1 of Manhole (맨홀-이상한 나라의 필) (KBS2, 2017), only not to be able to say a word when finally in front of her hours later. It’s also the manhole in front of this tunnel, that he’ll time travel just after berating himself (again and again) for another missed chance.
Flashback to the 1990s at the end of episode 16 of KBS2 The Best Hit (최고의 한방) (2017): J2’s MV for “Say It” was filmed here.
In episode 10 of Goblin/Guardian: The Lonely and Great God (쓸쓸하고 찬란하神 – 도깨비) (tvN, 2016-17), Kim Shin (Gong Yoo) and the Grim Reaper (Lee Dong-Wook) were seen doing the runway walk through this tunnel after buying green onions (대파) for Ji Eun Tak (Kim Go-Eun) and their moment was interrupted when a motorist passed between them.
This tunnel was also featured in MBC Every 1 web drama To Be Continued (투 비 컨티뉴드) (2015), in which K-pop group ASTRO teleports in time and Dream Knight (드림나이트) (2015) — starring GOT7.
To get here, go to Sinchon Station [신촌역 경의중앙선] on the Blue line, Exit 2. Turn left when getting out of the station and follow the road for 200-300 meters. The tunnel entry will be on your left hand side.
Some people come from the other side and use Megabox Sinchon [메가박스 신촌점] as landmark to find this place; you will need to follow the building and you will eventually end up at some stairs that lead you down to the tunnel.
If you visit, be aware that the tunnel has been repainted so you might not find the iconic pieces of Goblin. Actually, the walls were painted all in white in February 2018 as Yoora informs us but as Micka let’s us know graffiti is back (04/03/2018).
