Starfield Library at COEX: Free, and Genuinely Worth the Trip

COEX is a convention centre with one of the largest underground malls in Asia beneath it, and in 2017 the operator turned the central atrium — previously an unremarkable open space — into a library. The gesture was commercial and it worked: the mall got a landmark, and Seoul got a public reading room in a shopping centre.

The shelves run to thirteen metres, the upper reaches are decorative rather than reachable, and the working collection covers humanities, economics, design, hobbies and a substantial foreign-language section. A wall of current magazines from around the world sits at one end, and it is the part most people actually use.

There is no ticket, no membership and no requirement to buy anything. People sit for hours; students revise; visitors take photographs from the staircase. The library also hosts talks and small performances in the atrium, which is when the space is at its best — a bookshelf-lined room with a concert going on in the middle of a mall.

The photograph everyone comes for is taken from the upper level, looking down the length of the atrium with the shelves rising on both sides. On a weekday morning you will have it to yourself; on a Saturday afternoon there is a queue for the position.

Opening is 10:30 and the first hour is the quiet one. Late evening — after nine, with the mall thinning out — is the other good window, and the lighting is warmer.

Seasonal installations change the space: a large tree at Christmas, seasonal displays through the year, and periodic rearrangements of the central seating. If you are coming specifically for the room rather than passing through, it is worth a look at what is installed before you make the trip.

The practical note: COEX is underground and enormous, and the library sits at its centre. Come out at Samseong station on Line 2 and follow the mall signs rather than surfacing; from the street it is harder to find than it should be.

COEX holds an aquarium, a cinema, a K-pop-focused store and exhibition space, and food courts large enough to lose an afternoon in. Only the aquarium charges an entry fee among the things a visitor is likely to want.

Directly across the road stands Bongeunsa, a working Buddhist temple founded in 794, free to enter, with a 23-metre stone Buddha and a templestay programme. Walking from a thirteen-metre wall of books to a thousand-year-old temple takes five minutes and crosses eight lanes of traffic, and that juxtaposition is the most Seoul thing in Gangnam.

Lotte World Tower and its observatory are twenty minutes east by metro, which makes a sensible southern afternoon: library, temple, tower at dusk.
