Cheongnyangni 588, Miari Texas, and Yeongdeungpo's Sudogolmok: Where Seoul's Red-Light Districts Went

Even people who’ve been to Seoul a dozen times rarely know this: that gleaming 65-story tower next to Cheongnyangni Station — the one where you switch to the KTX — was, barely ten years ago, the most notorious red-light district in the city.

It had a name: Cheongnyangni 588. A lot number that became a proper noun, a place so established that any Seoulite knew exactly what it meant without explanation. And as I write this, in the summer of 2026, you can still hear the backhoes at the city’s last remaining cluster.

Why Were They All Beside Train Stations?

Spread a map out and the answer stares back at you. Cheongnyangni 588 was a three-minute walk from the platforms. Yeongdeungpo’s cluster sat right behind the station. The vanished Yongsan district faced the entrance. Jongno 3-ga’s old quarter — nicknamed Jongsam by locals — sprang up where intercity buses and streetcars once converged.

These weren’t districts that grew organically from nightlife. They bloomed at the exact spots where railways dumped people and money into the city. Men arriving from the provinces, dockhands, soldiers, and women with nowhere else to go — they all got off at the same platforms.

It started under colonial rule. Around 1904, during the Russo-Japanese War, Japan established an official red-light quarter called Shinmachi (新町, “new town”) in what’s now Mukjeong-dong in Jung-gu. Astonishingly, fragments of the colonial street grid still survive there. Japan’s licensed-prostitution system was transplanted wholesale into Joseon.

After liberation, the U.S. military government abolished licensed prostitution with the Public Brothel System Abolition Ordinance on November 14, 1947. But laws don’t make people vanish. The Korean War erupted, women who’d lost husbands and fathers flooded into the cities, camptowns sprang up around U.S. bases, and the shuttered brothels crept back into the alleys under a new name: unlicensed, unofficial, and everywhere.

Operation Butterfly — How Jongno 3-ga Vanished in Nine Days

The moment that pushed the trade out of downtown Seoul came in 1968.

On September 26, 1968, Seoul mayor Kim Hyun-ok was touring the Seun Sangga construction site when members of his party were propositioned by street sex workers. The mayor was reportedly shocked. He ordered a cleanup of the Jongno 3-ga area immediately. The operation had a name: Operation Butterfly (나비작전). The logic was simple — butterflies chase flowers, so instead of going after the women (the flowers), you go after the male clients (the butterflies). Faster that way.

After more than three decades, Jongsam was erased in a single sweep: the early hours of October 5, 1968, when riot police and demolition crews descended together. The problem was what came next. The displaced women moved beyond the city center, specifically to the banks of the Jeongneungcheon stream in Hawolgok-dong. That land had been a public cemetery during the Japanese occupation, then a shantytown after the war. There, Miari Texas was born.

The peak came in the 1980s. A booming economy, and the 1982 lifting of the nighttime curfew made the nights longer. Cheongnyangni 588, Miari Texas, and Cheonho-dong Texas became known as Seoul’s Big Three.

So What Stands There Now?

Here’s the three sites at a glance.

Cheongnyangni 588 — A Place Named After a Lot Number

The name is almost absurdly banal: 588 Beonji, Jeonnong-dong, Dongdaemun-gu. People called it Cheongnyangni because it sat beside the station, but administratively it was always Jeonnong-dong. Seoulites just used the number.

It disappeared especially fast. Demolition began in May 2016 alongside the redevelopment plan. By February 2018, relocation was 100% complete. On July 31, 2023, residents began moving into four residential towers — 65 stories, 226.5 meters — plus a 42-story landmark tower. The neighboring block got Hanyang Sujain Gracely, and the Cheongnyangni area saw one of the most dramatic skyline transformations in northeast Seoul.

Stand in the station plaza today and the contrast is almost dizzying. Cross one street from the foot of those glass towers and you’re in Gyeongdong Market and Cheongnyangni General Market, where the air still smells of medicinal herbs and elderly vendors spread ginseng roots on wooden pallets. It feels like two cities from different decades pressed against each other with a traffic light between them.

Miari Texas — From Public Cemetery to High-Rises

The area around 88 Beonji, Hawolgok-dong, Seongbuk-gu. No one’s sure where the “Texas” nickname came from, but the most cited theory points to the Western-saloon imagery — drinking downstairs, going upstairs, like a frontier-town bar in a cowboy movie. It’s also geographically closer to Hawolgok-dong than Miari proper; people just called it Miari because it sat on the approach to Miari Pass.

The final chapter closed very recently. On November 19, 2025, Seongbuk-gu began demolishing the brothel cluster within the Sinwolgok District 1 redevelopment zone (by that point, 111 of 115 businesses had completed relocation). On March 26, 2026, the remaining establishments were cleared, and the district officially announced the complete closure — after 70 years. Demolition was about 90% complete at that point. What’s coming: 11 towers, 46 floors above ground (6 below), 2,201 units including 197 public rental homes. The project uses a combined development scheme with Seongbuk District 2, about 3 kilometers away — the low-rise residential character of Seongbuk-dong is preserved by transferring unused floor-area ratio to this site.

Yeongdeungpo Sudogolmok — Where the Lights Haven’t All Gone Out

Behind Yeongdeungpo Station. The name, Sudogolmok, comes from the Sudo Inn that once stood out front. It’s Seoul’s last remaining concentration of sex-work establishments, which is why it receives the most media attention.

A 2022 Hankook Ilbo report counted 35 glass-fronted rooms, 20 so-called hwipari, 11 single-room units — 66 establishments with 146 people. The same investigation uncovered another fact: among the district’s roughly 170 lots, the South Korean government held ownership stakes in 20.6% of them. The same entity tasked with enforcing the law was also, in part, a landlord.

This area is on its way out too. After planning and public review in 2020, on June 10, 2021, the zone was officially designated a transit-oriented urban redevelopment district. The plan calls for 993 apartment units (132 public rental) and 477 officetel units, with buildings up to 150 meters. By late 2025, the alley entrances were equipped with ultra-high-definition CCTV; in July 2026, three more surveillance cameras were installed.

But let me be clear: this alley is not a place for travelers. That’s also why this piece doesn’t give a precise location. What’s worth seeing in Yeongdeungpo lies a few blocks away — the cavernous Times Square mall, the pre-dawn energy of Yeongdeungpo Market, and the aging print-shop alleys in between, all inside a single neighborhood.

Seoul’s Red-Light Districts, at a Glance

🗺️ The rise and fall of Seoul's major red-light districts (as of August 2026)

See the pattern? Every single site, without exception, now holds a high-rise apartment tower. There’s a cynical reading here that’s hard to dismiss: it wasn’t morality that cleared these alleys — it was land value. If these hadn’t been prime transit-adjacent lots, they wouldn’t have disappeared at this speed.

The Real Blow Came in 2004

Legally, the watershed was September 23, 2004 — the enforcement of the Special Act on Sex Trafficking. Crackdowns intensified and street-level trade visibly contracted.

But there’s a shadow here too. As the visible clusters shrank, the sex trade didn’t disappear — it dispersed into officetels, room salons, and online platforms. The critique that it simply went from visible to invisible remains hard to dismiss. Every time a glass door on the Yeongdeungpo alley goes dark, field reports document the same thing: the trade migrates, it doesn’t end.

What Remains

Seoul is a city that buries its past quickly. A trash mountain became a silver-grass park. An elevated highway became a walking path. Block 588 became apartments. Mostly, that’s a good thing.

Still: the lobby of the 65-story tower at Cheongnyangni Station has no plaque telling you what was here. The 2,201 units rising over Miari probably won’t either. Which is why the history of these alleys survives only in writing. If you travel through cities — really travel through them — knowing what stood where you’re standing matters. I think it’s one of the more important things to know.
