Every few decades since the 1880s, a different army has moved into the flat land south of Namsan. Qing Chinese troops camped here in 1882. The Japanese built a military base from 1904. American forces took it over in 1945 and stayed until 2018. Samgakji, the junction at the base’s western edge, spent all that time feeding and entertaining soldiers, and the neighborhood still shows it: a street of painters who once sold portraits to GIs, an alley of cod-soup restaurants, an offal grill with valet parking, and, since 2023, a children’s garden on land that was off-limits to Koreans for more than a century.

Next door, Sinyongsan has become one of Seoul’s busiest dining scenes. This guide stays mostly on the older side of the line.

The short answer

  • Where: Yongsan-gu, between Samgakji Station (Lines 4 & 6) and Sinyongsan Station (Line 4), next to the War Memorial of Korea.
  • The history: a garrison town for 140 years — Qing troops (1882), the Japanese army (from 1904), US forces (1945–2018) — and now the Yongsan Children's Garden on returned base land.
  • What to eat: cod soup in the daegu-tang alley, beef tripe at Pyeongyangjip, cheonggukjang at a 1970s Korean diner, then roasters and bakeries toward Namyeong.
  • Free stop: Yongsan Children's Garden — no reservation needed since December 30, 2025; closed Mondays.

Why is it called Samgakji?

Because it was a triangle. 삼각지 Samgakji means “triangle land.” Seoul city’s media hub explains that the name comes from the triangular junction where three major routes meet, on the main road between Seoul Station and the Han River.

In 1967 the junction got an elevated rotary road, which Seoul city’s media hub calls Korea’s first elliptical overpass, and in the 1960s the singer Bae Ho made the place famous with the ballad Doraganeun Samgakji (“Samgakji, going round”). For Koreans of a certain age, the name still brings up that song before it brings up the station.

A garrison town in five dates

  • 1882 — After the Imo military mutiny, about 3,000 Qing troops are stationed in Yongsan (Seoul Shinmun).
  • 1904 — During the Russo-Japanese War, Japan begins building a large military base in Yongsan. Samgakji sits on its western edge.
  • 1945 — US forces arrive to disarm the Japanese army and take over the base. US command headquarters is based here from 1957, and the Korea–US Combined Forces Command from 1978.
  • June 29, 2018 — US Forces Korea headquarters moves to Camp Humphreys in Pyeongtaek, 73 years after American troops arrived (Newsis).
  • May 2023 — Part of the returned land opens as Yongsan Children's Garden.

What is the Samgakji painters' street?

A street of framers and painters that started by selling art to American soldiers. According to a 2015 Seoul Shinmun feature, it began in the 1950s, when two shops near the junction started selling paintings to US servicemen, and boomed in the 1960s, when Korean artists painted copies of Western landscapes and portraits by the hundred for export and for GIs going home. At its peak the street had more than 250 painters and about 60 galleries; by 2015 about 40 galleries were left. Kyunghyang Shinmun has reported that painters who later became famous, including Lee Jung-seop and Park Su-geun, passed through the area when they were broke.

Today you’ll see the remains along Hangang-daero and the side streets near Samgakji: framing shops, art-supply stores and a few galleries with oil paintings stacked in the windows. They are working shops; you’re welcome to look, and most will frame a print while you have lunch.

Do you need a reservation for Yongsan Children's Garden?

Not anymore. When it opened in May 2023 on returned US base land, the garden required advance booking and ID checks. Seoul city’s media hub reports that since December 30, 2025 it has been fully open without reservations. It’s free.

Inside are wide lawns, sports fields and low buildings left from the base years. It’s only a small part of the planned Yongsan Park, most of which has not yet been returned or opened, so don’t expect to walk across the whole old base. Korean media have also reported disputes over soil contamination on parts of the wider site.
