Gwanghwamun Square & Cheonggyecheon Stream: Guide to Seoul’s Historic Center
I walk through Gwanghwamun Square probably twice a month for no particular reason other than it’s on the way to places and it’s one of those parts of Seoul where I still slow down. Even after years. The square is long—something like 550 meters from the palace gate to the main intersection—and at the far end you get Bukhansan’s peaks framed behind the Gwanghwamun Gate, and on clear days it’s one of those views where Seoul looks like it was designed by someone who understood grandeur.
This guide covers both Gwanghwamun Square and Cheonggyecheon Stream, which are connected—you can walk from one to the other in about ten minutes. Together they cover a lot of what people mean when they talk about “historic central Seoul.”
🏛️ Gwanghwamun Square
The Basics
Gwanghwamun Square (광화문광장) is a public plaza stretching along Sejong-daero from the main gate of Gyeongbokgung Palace down toward City Hall. It was redesigned and expanded in 2022—the sidewalk was widened, cars were pushed back, and it became more pedestrian-friendly than before. It’s significantly better now than when I first started walking through it.
The name Gwanghwamun (光化門) means roughly “Gate of Transforming Light”—which is I’m not sure how to explain this in English, but it’s a name that reflects the kind of moral and cultural illumination the palace was supposed to represent. Something like that. Korean historical naming conventions involve a lot of poetic weight.
What to See
King Sejong the Great Statue — The large bronze statue at the center of the plaza honors King Sejong (1397–1450), creator of Hangul (the Korean writing system) and one of the most significant figures in Korean history. His face is on the ₩10,000 note. The statue is 6.2 meters tall and commands the square in a way that doesn’t feel like a generic civic monument.
Underneath the statue there’s a free underground exhibition about Hangul’s development and Sejong’s contributions to Korean science, culture, and governance. It’s genuinely interesting and takes about 30 minutes if you read everything. Most visitors don’t know it’s there—I didn’t until I’d been past the statue probably twenty times.
Admiral Yi Sun-sin Statue — Further down the plaza, Admiral Yi (1545–1598) stands in full armor. He’s Korea’s most celebrated military figure—led naval campaigns against the Japanese during the Imjin War in the late 16th century and reportedly never lost a battle. The statue is dramatic and appropriately stern. The admiral has his hand on his sword hilt. He looks like he means it.
Gwanghwamun Gate itself — The main gate of Gyeongbokgung Palace terminates the plaza to the north. The Changing of the Guard ceremony runs here at set times (check the schedule at the Gyeongbokgung Palace website—it changes seasonally and is closed some days). The gate with Bukhansan behind it is, honestly, one of Seoul’s better views. Best in the morning light.
Best Times to Visit
Early morning, before the midday foot traffic kicks in. The square faces roughly south, so morning light comes from the east and lights up the gate and mountain backdrop nicely for photos. Late afternoon also works well.
The plaza hosts events throughout the year—seasonal decorations in winter, cultural performances, and occasionally political gatherings (Gwanghwamun has historically been a site for public demonstrations, which is part of its cultural meaning in Korea). Check what’s on if you’re visiting during a Korean holiday period.
💧 Cheonggyecheon Stream
Cheonggyecheon (청계천) is a 5.8-kilometer urban stream that runs through the center of Seoul, from near Gwanghwamun east toward the Hangang River. It’s a slightly unusual thing to recommend because it sounds unremarkable—a creek running through a city—but the walk along it is one of my genuinely favorite things to do in Seoul, and I don’t say that casually.
The backstory: Cheonggyecheon was covered over and converted to an elevated highway in the 1970s. In 2003, Seoul Mayor Lee Myung-bak oversaw a project to demolish the highway, excavate the stream, and restore it as a walking path. The ecological and social transformation this created is still debated in urban planning circles—it displaced markets and changed the neighborhood considerably—but as a public space, the result is excellent.
Walking the Stream
You enter at street level and descend stairs to the stream path, which runs below the surrounding streets. The water is shallow—I think about knee-deep in most sections, maybe less—and clean-looking, though I’m honestly not sure what goes into maintaining it. There are stepping stones to cross in some sections. Kids love this. Adults also love this but pretend they’re just observing.
The walk from the Cheonggyecheon Plaza start point (near Gwanghwamun) to the Gwanggyo (Gwanggyo Bridge area) is about 2–3 kilometers. You can walk further if you have time, or turn back at any point—there are stairs up to street level at regular intervals.
What the path is like:
- Shaded by the city on both sides—cool in summer, sheltered in light rain
- Lit up at night with small lights along the water—the evening walk is popular with couples and families
- Walls along the path have murals, historical tiles, and a famous section of reproduced ancient artwork (the “Daejanggeum” mural is a highlight if you walk far enough)
- Seasonal: cherry blossoms overhang parts of the stream in spring; lanterns are strung in November for a lantern festival
Honest caveat: I found the first time I walked it slightly underwhelming—I’d built it up too much and the crowds on a Saturday afternoon were thicker than I expected. Go on a weekday morning or evening, when it’s quieter. That’s when it’s actually calming rather than a slow shuffle behind a tour group.
The Cheonggyecheon Lantern Festival
Every November, the stream is lined with thousands of lanterns for the Seoul Lantern Festival—paper and LED lanterns themed around Korean history, zodiac animals, modern culture. It runs for about two weeks and is free to walk. It’s one of the better public events in Seoul and the crowds, while significant, move along the stream in a way that doesn’t feel claustrophobic like a festival in a contained space does.
I went two years ago with a friend who was visiting. We walked the full lit section, which takes about an hour including stopping to look at things, and came back another night for a second pass. Worth planning around if your November dates overlap.
🗺️ Combining Both: How to Spend a Day
Gwanghwamun and Cheonggyecheon are naturally combined because they’re close and complement each other—one is open sky and historical grandeur, the other is below street level and more intimate. A good half-day:
- Start at Gwanghwamun Gate in the morning (9–10 AM)
- Walk south through the plaza, stopping at both statues and the underground Sejong exhibition
- Continue south and find the Cheonggyecheon stream entrance (about 10-minute walk from the plaza)
- Walk the stream east for 30–60 minutes
- Exit at street level and head to Insadong or Bukchon for lunch
This itinerary is free except for coffee and food. The plaza and stream have no admission charge.
📍 Getting There
- 🚇 Gwanghwamun Square: Gwanghwamun Station, Line 5 (Exit 2 or 8)
- 🚇 Cheonggyecheon Plaza entrance: Gwanghwamun Station or walk 10 minutes from the square
- 🚇 Along the stream: Multiple subway stops connect to the path — Jongno 3-ga, Euljiro stations
💡 Tips
- ✅ Visit Gwanghwamun early morning for the best light and fewer people
- ✅ Don’t miss the underground Sejong exhibition — free, interesting, almost no one in it
- ✅ Walk the stream on a weekday for the calm version
- ✅ Evening walk along Cheonggyecheon is lovely — lit up, cooler air in summer
- ✅ Comfortable shoes — the stream path has uneven stones in sections
- ❌ Don’t try to see both at peak Saturday afternoon — crowds are significant
These two places together give you a pretty good cross-section of what Seoul is: a city that holds its historical identity carefully while completely reimagining it in public space. The palace gate, the modern plaza, the restored stream below street level. It’s all happening within about a kilometer of each other.

Cheonggyecheon is where I walk when I need to think. I work nearby and have probably done that stretch two or three hundred times. In summer the cool air from the stream is noticeably different from the sidewalk above.
