Daredevil Jaan Roose prepares to walk slackline high above central Seoul

Estonian aerial athlete Jaan Roose will attempt to cross a 160-metre long highline suspended 120 metres above central Seoul on Thursday.Roose, a three-time slackline world champion, will step out on to a narrow polyester ribbon between the Koreana hotel and the Dong-A Media Center, near the capital city’s famous Gyeongbokgung palace and Gwanghwamun square.The 34-year-old has made a name for himself slacklining dramatic urban environments, such as his 185-metre high feat between Qatar’s Katara towers.In 2024, he became the first person to slackline the strait of Messina between mainland Italy and Sicily, completing the 3.6km traverse despite a fall near the end, caught by his safety harness. Last month, he covered 14.7km over 12 hours on a line above the Danube in Bratislava, Slovakia.Large crowds in Seoul are expected to watch Roose walk the slackline – twice, at 1pm and 4pm local time – if the weather allows. The walk will be postponed if average wind speeds reach 10m/s or gusts hit 15m/s. Today’s forecast is sunny with light breezes.A woman in Warsaw, Poland, watches Estonian slackliner Jaan Roose cross a highline suspended above the city in 2026.

The walker sings, jokes and dances on the rope, trading banter with a clown on the ground as musicians play.
