Our church is located in Seoul city, in Yongsan District (Gu), in Hannam-dong. Our church is on one of the largest streets in the city: Hannam Road (Hannam-daero) and we are very close to the intersection with Itaewon Road (Itaewon-ro).
Our Address is: 148 Hannam-daero, Yongsan-gu, Seoul.
However some taxis and GPS sytems are more familiar with the old address system:
Make your way to Line 6 (brown line) and get off at Hangangjin Station. This station is the next station after (before) Itaewon. Exit the station from Exit #2. Walk straight out of the exit and follow the sidewalk as it curves toward a large pedestrian overpass. Take the overpass across the large street and as soon as you get to the bottom of the stairs you are directly in front of ILC. The walk from the subway is only around five minutes. A video showing this walk can be found here.
There is a bus stop directly in front of the church. It is bus stop #03160 and it is named Seoul Jungbu Institute of Techonology / Blue Square. It is serviced by routes: 142, 144, 402, 407, 420 and 6211. Typically bus stops are announced in Korean and English.
Directions will depend on where you are coming from. Apple Maps tends to work better than Google Maps which is blocked from giving car directions in Korea.
From the South: Head up the #1 Expressway and follow the signs for Hannam Bridge. Cross the bridge the church is on the right after passing one major intersection. If you pass the Harley Davidson building you have gone too far.
From the West. Come through Itaewon and turn right at the end of the street. Follow the traffic down to the intersection and make a U-turn underneath the overpass to go back the direction you came. The church is on the right hand side near the entrance to Itaewon.
