Lotte World Mall

The glass mall under Lotte World Tower, an aquarium and the Seoul Sky deck under one roof.

The shopping and dining complex at the base of the 123-floor Lotte World Tower.
Under one roof it holds the Seoul Sky observation deck, an aquarium, a concert hall and a cinema.
It connects straight into Jamsil Station underground, so you never step outside.
More a wet-weather day-out than a sight in its own right.

Nearest exit: Jamsil station (lines 2 and 8) links directly into the mall, so you never step outside.
