2026 Seosan Haemieupseong Festival Schedule · Drone Show · QR Hopae Experience, Before Visiting Haemieupseong with Kids

A 600-year-old fortress wall
with 1,000 drones lighting up the autumn sky 🏯

The 23rd Seosan Haemieupseong Festival
will be held for three days, from October 9 (Fri) to 11 (Sun),
throughout the Seosan Haemieupseong area.
Admission is free.

I’ve organized information from
the Ministry of Culture, Sports and Tourism’s regional festival guide,
the Seosan City Culture & Tourism website,
and announcements from Seosan City and the Seosan Cultural Foundation.

🎪 About the Festival

This year’s theme is
’HAEMI UNIVERSE 1421,
The Gate of Time Opens.’

In 1416, King Taejong and the 20-year-old Prince Chungnyeong
(later King Sejong) came to Haemi for military training (gangmu),
and the fortress, construction of which began the following year,
was completed in 1421.
This year’s festival follows this story over three days.

On the fortress wall, you can still see
the names of Chungcheong towns that helped build it,
engraved on the ‘Gakjaseongseok’ stones.
The opening ceremony lights up 23 large lanterns
using these stones as a motif.

The festival is hosted by Seosan City and organized by the Seosan Cultural Foundation.
This year, to protect the historic fortress,
there will be a drone show instead of fireworks.

✨ Schedule Highlights

Here are the daily operating hours from the Ministry of Culture, Sports and Tourism.
On the first day, the festival opens at 5 PM.

Elsewhere in the guide,
it also mentions 10:00~22:00.

The main stage programs by date
are based on announcements from Seosan City and the Foundation.

There are also daily performances
announced for the festival period.

Since the first day opens at 17:00,
please check the on-site schedule for any daytime performances on the 9th.

📱 What Can You Do with the QR Hopae?

Scan the QR code at Jin-nammun, the main gate,
and you’ll get a Joseon-era hopae (ID tag) on your phone.
From then on, you become a citizen of Haemieupseong in 1421.

The ‘R.P.G Haemi Return’
offers 135 missions inside the fortress,
including archery, gyeokgu (polo), pyeonchu (stick throwing),
and a civil service exam in a golden bell quiz format.
If you pass, you receive a red certificate,
and the top scorer in the civil exam becomes ‘Haemi Magistrate for a Day.’

There are also experiences with traditional costumes, horseback riding, archery, calligraphy,
and a ‘Fortress Construction Challenge’ where you find and photograph the engraved stones using an app.

Outside the fortress, in the East Gate Parking Lot area,
there’s the ‘Haemi Defense Road.‘
You can see models of Cheongung and Shingung missiles, Air Force tactical vehicles,
a drone simulator, and a drawing contest where kids’ turtle ship drawings
are scanned and displayed on a giant media wall.

🍢 Food and Night Market

Inside the fortress at ‘Town Marketplace,‘
you’ll find specialties from Chungcheong Province,
such as Gongju chestnuts, Seocheon mugwort rice cakes, Boryeong seaweed,
Geumsan ginseng, and Nonsan salted seafood.

Nearby at Haemieupseong Traditional Market,
the ‘Haemiitsung’ night market runs for the same three days.
Open daily from 11:00 to 22:00,
there are ham dishes, army stew, skewers, food trucks,
a flea market, and busking performances.
The opening ceremony is at 17:00 on the 9th in the market parking lot.

The paid gourmet program ‘600 Years Table’
is held in Dongheon Garden, limited to 60 people per day,
and costs 50,000 won per person.

🚗 Getting There & Parking

The address is 143, Nammun 2-ro, Haemi-myeon, Seosan-si.
Here are the directions from Seosan City’s tourism guide.

Schedules may change, so
please check the timetable before you go.

On Naver Place, Haemieupseong
is listed as having free parking (as of October 8).
There is no official information about temporary parking lots or shuttles during the festival.

👨‍👩‍👧 If You’re Visiting with Kids

Most daytime attractions are concentrated on the two weekend days.
You can see the air show at 13:00 on the 10th,
the Gangmu Parade at 15:00 on the 10th and 11th,
and then enjoy the drone show at night.

Since the hopae missions are on your phone,
make sure to bring extra battery power.

If you combine the fortress missions and night market,
you can enjoy a long day until 22:00.
It’s also a good idea to bring an extra jacket for your child.
