Millennium Square is the main exit of COEX Mall connecting with Line 2's Samseong Station.

COEX Mall was also designed by Gensler, under the theme "Unfolding Sky", emphasizing seamless flow and openness.

In addition, it serves as an event center, intended to host talk shows with authors, lectures with intellectuals and personalities, and concerts.
