A Massive Free Gallery Hidden Inside City Hall Station? Step Into Seoul Gallery Underground

A cultural space beneath the heart of Seoul

Right under one of Seoul’s busiest landmarks lies a place most people walk past without ever noticing.
Located on B1–B2 of Seoul City Hall, Seoul Gallery is a huge underground cultural complex where visitors can experience the city through immersive media, interactive exhibitions, and lifestyle spaces and the best part is that admission is completely free.

The moment you enter, the scale of the space is striking. A large information desk makes navigation easy, while a giant Haechi mascot welcomes visitors at the entrance, setting the tone for a family-friendly and globally accessible experience.

Interactive exhibitions that let you experience Seoul

The highlight of the venue is the main exhibition hall filled with media walls, digital installations, and interactive content that introduce Seoul from multiple perspectives.

A giant map of the city presents key districts through visuals and data, allowing visitors to explore Seoul in one place. Another popular attraction is the interactive global photo wall, where guests can take photos that place them inside Seoul-themed scenes.

One of the most talked-about displays compares Seoul’s transportation system with major global cities such as Tokyo, New York, and London, offering a unique look at how the Korean capital stands alongside the world’s leading urban hubs.

More than a gallery: shopping, kids’ zone, and even robots

Seoul Gallery is designed as a multifunctional cultural space rather than a traditional exhibition hall.

Visitors will find:

• A Seoul goods shop selling everything from keyrings and tumblers to towels
• A section featuring Seoul ramyeon, a fun and unexpected highlight
• A bookstore and snack bar for a quick break
• A dedicated kids’ zone for family visitors
• Cute guide robots that help guests navigate the venue

These elements make the space ideal not only for tourists but also for locals looking for a relaxing indoor destination.

Special performances during the Seollal holiday

During the Lunar New Year holiday, the gallery hosts small-scale live performances, adding a festive atmosphere for visitors spending Seollal in Seoul.

The venue will continue operating throughout the holiday period, making it a convenient cultural stop for those exploring the city during the long weekend.
