If you’re spending a day in Hannam-dong, chances are you’ll walk right past Blue Square Seoul — a huge cultural complex sitting between Itaewon and the Han River. Most foreign visitors come to this neighborhood for the Leeum Museum of Art, but Blue Square is worth knowing about too. It’s one of Seoul’s biggest performing-arts venues, and on the rainy day we visited, it turned out to be a lovely surprise for our whole family.
Here’s an honest local look at what Blue Square is, what’s on, and whether it’s worth a stop with kids.
What Is Blue Square?
Blue Square is a large cultural center in Hannam-dong, best known as one of Korea’s premier musical theatre venues. It has two main performance halls used for big-scale musicals and concerts, plus a separate exhibition space called NEMO that hosts art shows and pop-up exhibitions.
Because most performances here are staged in Korean, Blue Square isn’t usually on the typical tourist trail — but that’s exactly why it’s a nice window into how locals actually spend their evenings and weekends in Seoul.
The Musicals: Billy Elliot and Beyond
The heart of Blue Square is its musicals. During our visit, one of the productions running was Billy Elliot — the beloved show about a boy from a mining town in England who dreams of becoming a ballet dancer. It’s a globally famous musical (originally from London’s West End, with music by Elton John), and the Korean production is a long-running favorite that returns every few years. This season’s run wraps up at the end of July 2026, so if it’s on when you visit, it’s a real treat.
Even if Billy Elliot has finished by the time you’re reading this, there’s almost always something big on stage. Blue Square regularly hosts major long-running musicals — for example, later in 2026 the venue is set to stage large-scale productions like Elisabeth and The Phantom of the Opera. It’s always worth checking the current schedule before you go.
A quick note for foreign visitors: most musicals here are performed in Korean, so they’re best enjoyed if you already know the story or understand some Korean. Billy Elliot, with its music-and-dance-driven storytelling, is one of the more accessible options.
The Exhibition That Stole Our Hearts: Paper Pepper
The real highlight of our visit wasn’t a musical at all — it was an exhibition at Blue Square’s NEMO space by an artist known as Paper Pepper .
Paper Pepper is a hugely popular digital creator with millions of followers, famous for oddly soothing “paper ASMR” — recreating everyday objects entirely out of paper. The exhibition, titled “Sagak-Sagak Moments” — sagak-sagak being the crisp, snipping sound of scissors cutting paper — brought that world to life in person. Everything you’d normally see on a screen was there in three dimensions: food, cosmetics, little objects, whole miniature scenes, all painstakingly crafted from paper.
A Sweet Surprise: The Photo Zone at the Exit
One little detail that stuck with me: near the exit of the exhibition, there’s a shop selling merchandise and small keepsakes — and tucked into that area was a photo zone decorated with hanbok (traditional Korean dress) and other props.
It was such a charming, unexpected touch to end on. After wandering through a world of paper, stepping into a bright little corner styled with traditional Korean costumes made for a memorable last photo of the day. If you visit an exhibition here, don’t rush straight out — the exit area often has these thoughtful extras.
My Honest Take
We went as a family of four — my wife, our 6-year-old, and our 3-year-old — on a rainy day. Honestly, the weather could have ruined the outing, but Blue Square is connected directly to the subway station, so we stayed dry the whole way in. That alone made it a perfect rainy-day plan with little ones.
Inside the Paper Pepper exhibition, the part our kids loved most was a wall where children could color in the artwork themselves. It was easily the most popular spot in the whole show — every child there was crowded around it, coloring away and showing off their own little masterpieces. There were some genuinely talented kids in that crowd… but of course, I thought my child’s was the prettiest of them all.
That’s the thing about a place like this: it’s not just something to look at, it’s something kids get to be part of. If you’re visiting Hannam-dong with young children on a rainy day, this is exactly the kind of stop that turns an ordinary afternoon into a happy memory.
Getting There
Blue Square is in Hannam-dong, easy to reach by subway. The closest station is Hangangjin Station (Line 6), Exit 2, which connects almost directly to the complex — a real lifesaver in bad weather. It’s also very close to the Leeum Museum of Art, so the two pair perfectly for a single day in the neighborhood.
Is It Worth Visiting?
If you’re a musical lover who understands some Korean, Blue Square is a must — the productions are world-class. For international visitors who don’t speak Korean, the NEMO exhibition space is the real draw, since art shows need no translation and are often very family-friendly.
Either way, if you’re already coming to Hannam-dong for the Leeum, it’s well worth checking what’s on at Blue Square. On the right day — especially a rainy one — it can turn a museum outing into a full, memorable day out.
