Located in the so-called “truce village” of Panmunjom, roughly 65 km north of Seoul, the Joint Security Area (JSA) is probably the best-known place in the Korean Demilitarized Zone.

Here, North and South Korean forces stand face-to-face without any border fence separating them. The Military Demarcation Line is marked only by small white stakes planted in the ground and by a change in the color of the grass. The conscripts from the South (rumor has it they’re selected for their physical beauty to impress their northern counterparts) adopt strange taekwondo-like postures, while those in the north are usually older and have a more relaxed attitude. Seven huts housing meeting rooms are built straddling the border.

The JSA was not officially established by name in the 1953 armistice agreement, but was a direct consequence of it: a physical and operational center for providing a point of direct contact between the two enemies to settle current affairs, examine cases of armistice violations and exchange prisoners.

Its location in Panmunjom stems from the fact that the two main bodies responsible for enforcing the armistice—the Military Armistice Commission and the Neutral Nations Supervisory Commission—were required, under the agreement, to establish their headquarters in this former village where the text was negotiated and signed.

The JSA has often been the scene of bloody events and remains a completely surreal place.

For decades, this strange “village” with its carefully trimmed bushes and neatly mowed lawns on either side of a front line between two countries still technically at war has been open to tourism. The dress code for civilian visitors was strict: no shorts, no miniskirts, no sleeveless shirts, no tank tops, no ripped jeans, no baggy clothes, no sandals, no flip-flops, no sportswear or anything resembling military uniforms or bearing inscriptions deemed provocative. All of this was, in principle, to avoid fueling the North’s propaganda about Western decadence. Making gestures or speaking in the direction of Northern soldiers was also strictly forbidden.

Before entering the JSA, each visitor had to sign a waiver stating: “The visit to the Joint Security Area at Panmunjom will entail entry into a hostile area and possibility of injury or death as a direct result of enemy action”. There are no known cases of tourists being injured or killed by “enemy action”, but signing this document was part of the thrill.

No one really remmebers how this war zone had transformed over the years into a major tourist attraction. Tourism seems to have appeared incrementally, tied to political or military arrangements. The JSA received up to 100,000 visitors a year, before being closed to civilian tours in 2023 following the defection to the North of an American soldier during one of these visits.

The main buildings, the Panmungak in the north and the Freedom House in the south, round 100 metres apart, are linked by one of the 33 existing inter-Korean hotlines used for north-south communications. This telephone line used to be tested twice a day except during weekends and public holidays (the South called the North on odd dates, while on even dates it was the other way around).

However, North Korea has not picked up the phone since August 2021, in protest against joint South Korea-U.S. military exercises.

The JSA has been the scene of all kind of weird things, from fistfights to dramatic defections on both sides, and from gunfire battles to historic summits.

An unlikely meeting between North Korean leader Kim Jong Un and U.S. president Donald Trump happened here in 2019. Trump was invited by Kim to briefly cross the MDL, becoming the first U.S. president in History to step foot into North Korean territory.

One year earlier,  in April 2018, a historic inter-Korean summit took place in the JSA. North Korean leader Kim Jong-un shook hands with South Korean President Moon Jae-in and crossed over the MDL, marking the first time a North Korean leader has set foot in Southern territory since the Korean War. Both men held hands and crossed back over to the North briefly before returning to the South. The following month, Kim and Moon met again in the JSA, this time on the North Korean side.

Two years earlier, the JSA had been the scene of the dramatic defection of a North Korean man, Oh Chong Son.

The defector drove a car at full speed, forced his way through the JSA and found himself mired a few meters from the border. He then jumped out of the vehicle under fire from North Korean soldiers, managed to sprint across the demarcation line and, critically wounded, took refuge behind a low wall where he was rescued by the South Korean army. He survived, and the surgeons who operated on his wounds extracted worms up to 27 centimetres long from his intestines – a consequence of North Korea’s use of human excrement as fertilizer.

Years later, he was arrested for drunk driving in South Korea, where he had failed to integrate.

In 1984, a translator from the Soviet embassy in Pyongyang, Vasily Matuzok, ran suddenly across the border while on a DMZ tour from the North, triggering a 40 minute gunfight that left one South Korean and three North Korean soldiers dead.

Twenty minutes after the end of the battle, several gun shots were heard in the north. It is believed that the North Korean JSA commander and one of his deputies were summarily executed by their political commissioners for failing to prevent the defection.

Similarly, shortly after Oh’s defection in 2017, the military in the south heard the sound of a gunshot. In all likelihood, the North Korean JSA commander had preferred to commit suicide rather than face the terrible punishment for having failed to prevent the escape.

Other cases of defections through the JSA include a Chinese army officer and his wife in 1989. In the opposite direction, seven American soldiers have defected to the North through the DMZ since the end of the Korean War. The last one so far was private Travis King, a 23 year-old American serviceman with serious disciplinary problems, in July 2023.

King, who was supposed to to take a flight back to the U.S. after serving jail time in South Korea for assault, managed to escape from Incheon Airport, to join a JSA tour and to defect by running across the border, howling with laughter, in front of his stunned group mates. He was detained in North Korea for over two months, then deported to China following secret negotiations and repatriated to the U.S.

The JSA is also the place where people who have crossed the border, deliberately or by accident, are repatriated. On a regular basis, military personnel and North Korean fishermen who have involuntarily found themselves in South Korean waters and have expressed their desire to return home have been able to do so via the JSA.

But sometimes these returns are less peaceful. In 2019, the South Korean government was harshly criticized for forcibly repatriating through the JSA two North Korean fishermen who had defected to the South after alledgely murdering with hammers their 16 shipmates. Footage published at the time show the two men restrained and blindfolded, with one of them trying to resist as they were dragged to the demarcation line where the North Korean military awaited them. Their fate remains unknown to this day, but it is likely that they were swiftly executed.

Other highlights in the history of the JSA include the return to South Korea of two activists, reverend Han Sang-ryol in 2010 and Roh Su-huin in 2012,  who had made unauthorized visits to North Korea to promote reunification. Both were arrested on the spot by the South Koreans after they crossed the Military Demarcation Line and served lengthy prison sentences. In the case of Roh Su-huin, he was sent off at the JSA by a large group of North Korean civilians waving the flag of reunified Korea and carrying bouquets of flowers, who hurled insults and fiercely protested his arrest after he crossed the border.

Seven blue and grey huts straddle the Military Demarcation Line. The blue belong to the United Nations Command (UNC) and the grey to the Korean People’s Army (KPA). Two of the huts are used as meeting rooms for the Military Armistice Commission (MAC), a 10-member bilateral body set up to manage the implementation of the 1953 Armistice Agreement and investigate violations. However, North Korea has boycotted the meetings since 1991, when South Korean officers were appointed by the UNC as senior members of the MAC in replacement of U.S. officers (North Korea claims that only signatories to the Armistice Agreement, of which South Korea is not a part, can be representatives).

Another hut is used by the Swiss and Swedish soldiers of the Neutral Nations Supervisory Commission (NNSC), whose existence North Korea ceased to recognize in 1995. The Swiss and Swedish members of the NNSC continue to meet there once a week. They are the last regular users of the place.

In other words, these conference rooms are not used much anymore. This has not always been the case: in the years following the Korean War, meetings between the two sides were held almost every day, and journalists were allowed to watch them through windows. Fistfights between North Koreans and Americans outside the huts were not uncommon, sometimes resulting in serious injuries.

Visiting one of these huts means technically stepping into North Korea, as the border crosses the negotiations table. In some cases, North Korean soldiers used to stare at the visitors with curiosity and take pictures of them through the windows. A South Korean soldier guards the north door at all times during the visit in case a tourist is tempted to do something stupid.

The JSA was originally a neutral territory where soldiers from both sides could move freely and where firearms were theoretically banned. Since August 1976, when two American servicemen were murdered with axes by North Koreans during a clash over pruning a tree in the JSA, everyone has remained on their own side of the demarcation line.

This meant that the North Korean part of the JSA suddenly found itself cut from the rest of the country, its only access until then being via the Bridge of No Return in the southern part of the JSA. The North rushed to build a replacement structure on its side that was named the 72-hour Bridge because that was the time in which it was hastily constructed. People from the North now enter the JSA via this bridge.

The JSA was also where the massive prisoner exchanges took place at the end of the Korean War, across the Bridge of No Return that spans a stream marking the border. The name originates from the final ultimatum that was given to the prisoners about to be repatriated: they could either remain in the country of their captivity, or cross the bridge to return to their homeland. However, once they chose to cross the bridge, they would never be allowed to return.

At either side of the bridge are guard posts of the respective countries. The North Korean one is called KPA#4 while the United Nations Command checkpoint was called CP#3. It was abandoned in the mid-1980s after numerous attempts from the North Koreans to grab UNC personnel from it and drag them across the bridge into their territory. Because of this permanent abduction threat and its proximity to the North, the CP#3 was referred to as “The Loneliest Outpost in the World”.

I first visited the JSA in November 2005, with a group of Japanese tourists. From their main building, the Panmungak, the North Koreans watched us closely with binoculars. A group of Chinese were touring the north side that day too. There was also a bunch of North Korean soldiers and a guy in communist-style civilian clothes lurking in the bushes a few meters north of the border. The atmosphere was really strange.

During the 2018 détente, the two Koreas signed a series of agreements providing for the demining and disarmament of the JSA, and to make the area a “peace tourism” zone where civilian visitors would be allowed to wander both sides of the demarcation line from 9 a.m. to 5 p.m. to recall the historic gestures of Kim Jong Un and Moon Jae-in at their April 27 summit.

The agreement also lifted the restrictions about what the tourists can wear. Unfortunately, the Covid-19 pandemic followed by renewed tensions between the two Koreas prevented this project from materializing. And on the South side, tours for foreigners in the JSA remain suspended at this date after the bizarre defection of Travis King in 2023. Visits —reserved exclusively for South Korean nationals— cautiously resumed in the spring of 2025. At a time when wannabe influencers are willing to do anything to gain views on social media, it is understandable that the military is reluctant to reopen this ultra-sensitive border site to everyone.

One of my military friends in Seoul has described the JSA as a “circus”. It certainly is, but it’s also one of the most bizarre places in the world, and a visit to it leaves a lasting impression on anyone lucky enough to experience it.
