COEX & Starfield Library: Why This Is One of Seoul’s Most Popular Modern Attractions
One of the places that appears most frequently on foreign travelers’ Seoul itineraries these days is COEX in Gangnam.
Years ago, most people simply thought of COEX as a large shopping mall. Today, however, it has become one of Seoul’s must-visit attractions thanks to its unique combination of:
K-pop culture
Massive digital displays
Futuristic city vibes
Stylish indoor spaces
Instagram-worthy photo spots
Two attractions in particular have helped make COEX famous worldwide:
The COEX K-POP Square LED Screen
Starfield Library
Both have become symbols of modern Seoul and are often featured in travel videos, social media posts, and K-drama-inspired travel guides.
As someone who has lived in Seoul for over 30 years, I find it fascinating that places I once walked past without much thought now leave visitors saying, “This feels like a futuristic city.”
Here’s a realistic guide to the most popular attractions at COEX and some useful tips for first-time visitors.
1. COEX K-POP Square: Seoul’s Famous Giant LED Screen
The most iconic attraction around COEX is undoubtedly the massive outdoor LED display known as the K-POP Square.
Its famous 3D wave animation became a global sensation and has turned into one of Seoul’s most recognizable landmarks.
Many international visitors describe it as:
“Seoul’s version of Times Square”
“A glimpse of the future”
“A place straight out of a K-pop music video”
When you visit at night, the atmosphere becomes even more impressive.
The combination of:
Giant digital advertisements
Neon lights
Gangnam’s skyline
Crowds of locals and tourists
creates a uniquely Seoul experience.
K-pop fans especially enjoy visiting because idol advertisements frequently appear on the giant screen.
How to Get There
The easiest way is by subway.
Option 1
Subway Line 2
Samsung Station
Exit 5 or 6
Option 2
Subway Line 9
Bongeunsa Station
Exit 7
Both stations connect directly to the COEX area.
Best Time to Visit
Personally, I recommend visiting:
Around sunset
After 7 PM
The screen looks much more dramatic after dark.
If it happens to be raining, the reflections on the pavement create an almost cinematic atmosphere.
2. Starfield Library: Seoul’s Most Famous Indoor Space
Once inside COEX Mall, you’ll find one of Seoul’s most photographed attractions: Starfield Library.
Most first-time visitors have the same reaction:
“Is this really a library?”
The towering bookshelves that stretch toward the ceiling are surprisingly impressive in person.
The combination of:
Floor-to-ceiling bookshelves
Natural lighting
Modern architecture
Open public space
creates an atmosphere that feels both relaxing and futuristic.
Today, Starfield Library is known as:
A popular Instagram spot
A favorite K-drama-style photo location
A frequent stop for travel vloggers
In fact, there are often more people taking photos than reading books.
How to Find Starfield Library
The library is located in the center of COEX Mall.
The easiest route:
Samsung Station Exit 5 or 6
Follow the underground passage into COEX Mall
Walk approximately 5 minutes
The signs are well marked, making it easy for first-time visitors to find.
Practical Tip
Weekends can be extremely crowded.
Especially during:
Saturday afternoons
Public holidays
Evening hours
you may even find lines forming for photos.
If you prefer a quieter experience, try visiting:
Weekday mornings
Weekday afternoons
Why Foreign Visitors Love COEX
After talking with many international travelers, I’ve noticed that people don’t visit COEX simply because it’s a shopping mall.
What they really enjoy is the experience of modern Seoul.
Visitors often mention:
Seoul’s futuristic atmosphere

Modern architecture
Clean and comfortable indoor spaces
Bright and energetic streets at night
For many travelers, COEX offers one of the easiest ways to experience the modern side of Korea.
Nearby Places Worth Visiting
If you're already in Gangnam, several other attractions are located nearby.

Located directly across from COEX, Bongeunsa offers a fascinating contrast between traditional Korea and modern Seoul.

Local Tips From a Seoul Resident
1. Use Naver Map Instead of Google Maps
While Google Maps works in many countries, navigation in Korea is much more accurate with:
Naver Map
Kakao Map
These apps provide better information for:
Subway exits
Bus routes
Real-time navigation
2. Visit at Night for the Best Photos
The K-POP Square display is far more impressive after dark.
The combination of:
Digital billboards
Neon lights
Gangnam’s skyline
creates some of the best urban photography opportunities in Seoul.
3. Wear Comfortable Shoes
Many visitors underestimate how large COEX Mall actually is.
It’s easy to spend several hours exploring the mall, library, restaurants, and surrounding attractions.
Comfortable walking shoes are highly recommended.
Final Thoughts
Modern Seoul is no longer just a city of shopping and sightseeing.
For many visitors, it has become a destination where K-pop culture, technology, architecture, and urban lifestyle come together.
COEX and Starfield Library perfectly represent that side of Seoul.
They offer visitors a chance to experience:
Modern Korean culture
Futuristic city design
Gangnam nightlife
Contemporary Korean architecture
As someone who has lived in Seoul for decades, I sometimes forget how extraordinary these places can look through the eyes of a first-time visitor.
If you're planning a trip to Seoul, COEX deserves a spot on your itinerary—not just as a shopping destination, but as one of the best places to experience modern Korea.
