Estonian aerial athlete Jaan Roose completed a 160-metre slackline walk suspended 120 metres above central Seoul on Thursday, according to The Guardian. The crossing took place between the Koreana hotel and the Dong-A Media Center, near Gyeongbokgung palace and Gwanghwamun square in South Korea's capital.

Roose, a three-time slackline world champion, navigated the narrow polyester ribbon as part of an attempt that The Guardian describes as his first of two planned crossings. The walk represents a high-altitude feat of balance and nerve. At 120 metres above ground level, the slackline positioned Roose high above the busy urban landscape of central Seoul.

The stunt took place in one of Seoul's most recognisable locations, near the historical Gyeongbokgung palace, a 14th-century royal residence that draws tourists and locals alike. The proximity to major landmarks and populated city squares added visibility to the event.

The Guardian identifies Roose as holding three world championship titles in slackline, positioning him among the sport's elite practitioners. Slacklining, the discipline of walking or balancing on a suspended flat webbing rope, has grown into a competitive sport with international championships. At 120 metres, this particular walk ranks among the highest urban slackline attempts on record.
