What is actually being built on the DMZ?

A Berlin institution's founding idea is about to be tested at the most guarded border on earth. A cultural organisation called PERMIT, led by director Joon Kwak, wants to turn Goseong County, the only South Korean county still split by the Demilitarised Zone, into a permanent cultural destination. The launch vehicle is SUNN Festival, and the plan went public on July 3 at the Goseong Specialised Culture Strategy International Forum.

The date they chose for the festival says everything. SUNN is set for October 3, 2026, the Tag der Deutschen Einheit, the day Germany marks its reunification. Kwak is blunt about the goal: build a sustainable cultural ecosystem with local creators in Goseong, not just import ours for one festival and leave.

Why is Tresor's founder in this?

Because he has done a version of it before. Dimitri Hegemann joined the forum through a pre-recorded video interview, and his name alone is the thesis. Hegemann opened Tresor in 1991 in the flooded vault of a bombed-out department store on Leipziger Strasse, meters from where the Berlin Wall's death strip had just come down. His life's argument is that techno did not merely soundtrack a divided city healing, it physically reclaimed the dead space that division left behind.

The German Embassy in Seoul is backing the project, and the sound artist Nik Nowak is collaborating. Nowak is the right man for it: his work digs into the sound politics of the Cold War along the fault lines of divided Germany and Korea, treating borders as instruments as much as barriers.

"A line doesn't only divide, a line connects. We want to take the border that has always meant separation and treat it as a stage instead of only a line of control." Joon Kwak

Can a festival actually change a militarised border?

That is the fair question, and the honest answer is that nobody knows yet. One day on October 3 disarms nothing. But the framing is deliberate and it is not naive. Goseong is chosen because it is the wound, and the German Unity Day date is a bet that a border can be re-read rather than only patrolled. The real test is not the first edition, it is year two and year five, and whether the people of Goseong end up owning the thing or just watching it.
