Lotte World Tower in Songpa-dong dominates the skyline of southeastern Seoul, its tapered glass form visible from much of the city. The 123-floor building contains offices, a hotel, residences, and the Seoul Sky observation deck on floors 117-123. The views from the top are the most expansive in the city — on clear days you can see beyond the urban area to the mountains in all directions.
The adjacent Lotte World Mall is one of the largest shopping centres in Asia, and Lotte World itself (the theme park and amusement complex next door) provides context for the scale of development in this part of Songpa. Jamsil Station (Lines 2 and 8) is the nearest subway stop.
