It’s a weird feeling, standing on a patch of land that feels like suburban Ohio while looking at the N Seoul Tower looming right over the fence. For decades, Yongsan Garrison South Korea has been this massive, walled-off anomaly in the dead center of one of the world’s most densely packed cities. It’s basically a piece of the United States plopped into the heart of Seoul. You've got Taco Bells, bowling alleys, and American-style ranch homes sitting on some of the most expensive real estate on the planet. But things are shifting. Fast.
The history here is heavy. Most people don't realize that before the Americans moved in after World War II, the Imperial Japanese Army used this same spot as their headquarters during the occupation. It’s been a seat of foreign military power for over a century. That’s a long time for a city to have its heart occupied by someone else. Now, as the U.S. military completes its massive migration south to Camp Humphreys in Pyeongtaek, the "Forbidden City" of Seoul is opening up.
The Massive Scale of the Yongsan Relocation
The scale of Yongsan Garrison South Korea is hard to wrap your head around if you haven’t seen it from the air. We’re talking about roughly 630 acres. To put that in perspective, it’s nearly the size of New York’s Central Park. For the longest time, if you were a local, you just drove around it. You didn't go through it. It was a giant gray hole on the map where GPS sometimes got a little wonky.
The move to Camp Humphreys wasn't just about giving the soldiers better barracks. It was a strategic, multi-billion dollar shift. The Land Partnership Plan (LPP) and the Yongsan Relocation Plan (YRP) were the formal frameworks that set this in motion years ago. Logistics were a nightmare. Moving tens of thousands of personnel, their families, and enough equipment to run a small country takes time. Honestly, it took way longer than anyone initially predicted because of political shifts and the sheer complexity of cleaning up a century-old military site.
What’s actually inside those walls?
If you were lucky enough to get a pass back in the day, the vibe was pure Americana. You’d see yellow school buses driving kids to Seoul American High School. There was a commissary that smelled like Kirkland signature products and a Dragon Hill Lodge hotel that served a mean Sunday brunch.

But beneath that suburban veneer lies a complicated environmental reality. Decades of fuel leaks and industrial use have left the soil in some areas pretty rough. This has been a major sticking point between the South Korean Ministry of National Defense and the U.S. forces. Who pays for the cleanup? How clean is "clean enough" for a public park? These aren't just bureaucratic questions; they are multi-million dollar legal battles that have delayed the full handover of the land.
The Birth of Yongsan Park
So, what happens to 630 acres of prime real estate? The Korean government decided it won't be luxury condos or a new financial district. Instead, it’s becoming Yongsan Park.
This is huge. Seoul is a concrete jungle. It’s beautiful, sure, but it needs more green space. The vision for the new park is to create a "healing" space that acknowledges the site's dark history while looking forward. They aren't just bulldozing everything, though. Many of the old red-brick colonial buildings from the Japanese era and the mid-century American barracks are being preserved. It’s going to be a weird, beautiful hybrid of a museum and a forest.
The partial openings you can visit right now
You don't have to wait until 2027 or 2030 to see some of this. Sections of the former Yongsan Garrison South Korea are already open to the public.

- The Former General Officers' Housing Area: This is a surreal spot near Seobinggo Station. You can walk through the old housing complexes where high-ranking U.S. officers lived. They’ve turned some of the houses into exhibition spaces and cafes. It feels like a movie set.
- The Yongsan Park Pilot Opening: Occasionally, the government opens larger stretches for "tours." You have to book these in advance, and they fill up in seconds.
- The National Museum of Korea: While not part of the garrison itself, it sits right on the edge. The museum’s future expansion is tied directly to the land being returned.
Why this matters for the average traveler or expat
If you’re visiting Seoul, you’re likely spending time in Itaewon. Itaewon exists because of Yongsan Garrison. All those tailor shops, international restaurants, and bars were built to serve the GIs. As the garrison empties out, Itaewon is going through a massive identity crisis. It’s becoming more "local" and less "military."
You'll notice the change in the crowds. The rowdy bars are being replaced by high-end coffee shops and designer boutiques. It’s gentrification on steroids, but it’s also making the area feel more integrated with the rest of the city.
Realities of the environmental cleanup
We have to talk about the dirt. It’s the least sexy part of the Yongsan Garrison South Korea story, but it’s the most important. Soil contamination—mostly petroleum hydrocarbons and lead—is a serious issue. Organizations like Green Korea United have been vocal for years about the transparency of the cleanup process.
The South Korean government is under immense pressure to ensure the park is safe for children to play in. This means the full "Central Park" vision is still a decade away. They are doing it in phases. They test, they scrape, they treat, and then they open. It’s a slow, methodical reclamation of sovereignty.

Navigating the transition
If you want to see the "Old Yongsan" before it’s completely gone, you need to head to the perimeter. Walk the brick wall from Noksapyeong Station toward Samgakji. You can still see the guard towers and the concertina wire. It’s a stark contrast to the gleaming glass skyscrapers of the nearby HYBE headquarters (where BTS is based).
That’s the thing about Yongsan. It’s a place where history is layered like an onion. You have the Joseon Dynasty heritage, the Japanese occupation, the Cold War presence of the U.S., and now the hyper-modern Korean future, all overlapping in one square mile.
Actionable insights for your next visit
- Check for "Pilot Openings": Before you go, check the official Yongsan Park website (usually managed by the Ministry of Land, Infrastructure and Transport). They often have temporary openings for specific zones.
- Visit the War Memorial of Korea: It’s located right next to the garrison. It provides the necessary context for why the U.S. military was there in the first place. It’s one of the best museums in the city.
- Explore the "American Village": Take the subway to Seobinggo Station, Exit 1. Walk about ten minutes to the former officer housing. It's the most accessible part of the garrison and the best place for photos that look like you’re in 1980s America.
- Watch the real estate: If you’re looking to invest or stay long-term, the areas of Huam-dong and Namyong-dong are the ones to watch. As the walls come down, these formerly "blocked" neighborhoods are becoming the hottest spots in the city.
The transition of Yongsan Garrison South Korea isn't just a military move. It’s a city finally getting its heart back. It’s going to take time, and there will definitely be more political arguments over soil and money, but the wall is finally coming down.
Stay updated on the construction phases through the Seoul Metropolitan Government's English portal. The "Yongsan Legacy" project also has a great archive of photos and stories if you want to see what life was like inside the gates before the move.
The "Forbidden City" is opening up. Go see it while the layers of history are still visible.
