Unfortunately, in Korea there is no reliable online map with English directions and labels. At least, Google Maps provides foreign-language speakers with more convenient user interface (UI). However, note also that the map data of Korea in Google Maps has not been updated for several years and thus is slightly inaccurate.
We are in the Asan Science Building (아산이학관), at the address 145 Anam-ro Seongbuk-gu, Seoul 02841, Korea.
Using Google Maps
The best way to get around in Seoul is to use the subway trains. To get here, take Line 6 and get off at the Anam (안암) station. When you get out of the station through Exit 4 and walk 100 meters or so, then you can see the Science Campus on your left. Find the Asan Science Building (아산이학관) on the campus. See the map below for more details.
