BTS were most recently in Seoul, South Korea , where they just made their big comeback with a huge concert at Gwanghwamun Square after finishing their military service and a nearly four‑year break from the stage.

Quick Scoop: Where Was BTS?

In March 2026, BTS reunited in Seoul for a large-scale, Netflix-streamed comeback concert at Gwanghwamun Square, drawing tens of thousands of fans. This show marked their first full-group performance in almost four years, following each member’s completion of South Korea’s mandatory military service.

Seoul is also the group’s long-time base: it is where BTS originally formed, trained, and held many of their most iconic concerts and shoots over the years. Around their 2026 comeback, the city has effectively turned into a celebration zone, with events and landmarks highlighting BTS’s return.

Fans online are basically saying: “They’re back where it all began – Seoul is purple again.”
