The Age of Gunpowder at Jinjuseong Fortress

Most people walking around Jinjuseong head for Chokseongnu Pavilion, where you can look down on the Namgang and find a good place to take a picture. It’s easy to miss the building farther inside the fortress. I noticed it after going around the walls. It was Jinju National Museum.

I went in with the modest expectations I usually bring to a museum I happen to have time for on a trip. Inside, I had the sense that the exhibition continued the walk I’d just taken. The wall and river had become part of its setting.

The museum has a regional collection and a distinct focus on the Imjin War. Its displays look at the arms, technology and conduct of the war across Joseon Korea, Japan and Ming China.

What It Means to Be Inside the Fortress

Some of the fiercest fighting of the Imjin War took place at Jinjuseong. The museum is in a position to interpret that history on the ground where two sieges took place.

Walk the walls before going in and the strategic position is easier to grasp. The Namgang offers a natural barrier, and there are limited ways to approach. Inside the museum, the numbers in a battle account start to describe something you can picture. The weapons are of types that had a place in fighting on terrain like the ground you’ve just seen.

How the Museum Is Arranged

There are three main exhibition areas: a hall on the Imjin War, a regional history and culture hall, and a space for special exhibitions.

The Imjin War hall is central to the museum. Weapons, paintings and records show how Joseon, Japanese and Ming forces were organized. The displays put Japanese matchlocks and Ming tactics alongside Joseon arms. It makes it possible to see how technology and organization affected a battle.

The history and culture hall has a different rhythm, with objects from the Gaya confederacy and other material from western South Gyeongsang Province. It gives you time to shift your attention after the military exhibits.

When I visited, the special exhibition was The Age of Gunpowder in Joseon.

The Age of Gunpowder in Joseon

The exhibition followed the way Joseon adopted and developed gunpowder weapons. It had a prologue, two main sections and an epilogue.

Prologue: Before Gunpowder Became a Weapon

The exhibition began with alchemy. Its account traced gunpowder’s origins to Chinese Daoist practitioners seeking elixirs of longevity. Books including the Baopuzi and the Bencao Gangmu were presented alongside materials used in gunpowder.

The opening gave an example of how far a substance can travel from the purpose that first brought it to someone’s attention. Alchemical experiments, signals and warfare all belonged to different stages of the story.

Part One: Developing Gunpowder Arms

The first section covered developments from late Goryeo into early Joseon. It followed work under Kings Sejong and Munjong, changes to the chongtong system under Sejo and Seongjong, and the use of gunpowder arms during the Imjin War.

Early hand cannons, medium chongtong and seungja chongtong showed how much the scale could vary. Some firearms were small enough to hold. Laying them out together showed what standard designs and trained crews could contribute in addition to the number of people fielded.

The museum gave particular attention to Joseon’s work to study, manufacture and standardize the weapons. The defensive campaigns of the Imjin War look different once you can see what had been prepared in advance.

Part Two: The People Behind the Weapons

I spent longest in the part of the exhibition that looked at the people making the weapons.

Gunpowder could be in short supply. Artisans tried different methods of producing it and put the results to use. The exhibition introduced the state armaments bureau, the Gungisi, which oversaw some of that work. A weapon leaving a workshop was also part of a system the state had to maintain.

I hadn’t expected to see chongtong associated with fireworks and rituals to ward off misfortune. In that setting, the sound and fire had a different purpose from the one they had in battle.

Epilogue: From the Hand Cannon to the Rifle

The final video followed small firearms on the Korean Peninsula from early hand cannons to modern rifles. It gave the older objects a place in a much longer effort to work out how such a device could be made and used.

The interactive Joseon weapons area had models and explanations that made the material easier to follow, including for children.

Why I Stayed Longer Than I Expected

I thought half an hour would be enough. I stayed longer because it was easy to follow the story from the first room to the last.

The view outside changed afterward. The walls, river and terrain all had something to do with what I’d just seen. A visit to the museum had changed what I could see in the landscape.

Chokseongnu and the Namgang draw people into the fortress. For someone interested in the Imjin War, the museum gives those familiar views another reason to matter.

An Extension of the Walk Around Jinjuseong

The museum belongs in the same visit as the fortress. You can come back out and walk some of the same ground with a different idea of how it worked.

During the lantern festival, there’s a further change of view. You can spend the afternoon with the history inside and come back to the river after dark.
