The Walk Between: How One Estonian Slackliner Is Turning Warsaw's Skyline Into His Stage

On May 31, 2026, Jaan Roose will step off the edge.

The Estonian highliner — a practitioner of the discipline that transforms a flat strip of webbing into a walking surface suspended in open air — plans to traverse roughly 180 meters of line between two of Warsaw's tallest towers, according to an announcement posted to the event's Telegram channel on May 28. The stunt, branded under the Red Bull "Gives Wings" banner, will place Roose above the Polish capital's streets at a height roughly comparable to a 55-storey building. No precise public confirmation of the exact tower locations had been posted to the channel as of this article's filing.

Roose, 33, has spent the better part of a decade accumulating a documentation trail of longline crossings across Estonia and Central Europe — a reputation earned through competitions in the Slackline World Cup series and a series of high-altitude personal projects that have taken him across the Baltic region. The Warsaw event, if completed successfully, would represent one of the most technically demanding urban traversals in recent European slackline history.

What the event actually involves

The mechanics of what Roose is attempting are straightforward in description but singular in execution. A highline is, in essence, a slackline rigged horizontally between two anchor points — in this case, building facades or structural elements at or near the towers' upper levels. Unlike a tightrope, a slackline has give; the line sags under the walker's weight and oscillates with each step. At 180 metres — the figure cited in the May 28 announcement — the pendulum effect is amplified by the line's length, demanding constant micro-adjustment from the walker.

Equipment for an endeavour of this scale typically includes a weighted backup line in addition to the primary walking line, distributed anchor points along the building faces, and a safety tether for attachment during transit. Whether Roose will walk the full distance without stopping is not yet confirmed in the public record. Neither the Telegram announcement nor any independent verification as of this filing clarifies the precise rigging arrangement, anchor specifications, or weather contingencies governing the attempt.

Highline attempts of this profile usually require coordination with city authorities, building management, and emergency services. The sources reviewed for this article did not document whether Warsaw city officials had been contacted, nor whether any public-road or public-space closures had been ordered in connection with the stunt.

Why these stunts capture the imagination

Urban slacklining occupies a peculiar intersection of physical risk, architectural spectacle, and social media logistics. The discipline presents a genuine test — a human body suspended above the ordinary ground of a city, with nothing between the walker and gravity — but one that is legible to a non-specialist audience in a way that, say, competitive longboarding or deep-water soloing is not. The visual grammar of walking a line between skyscrapers is immediately legible as extraordinary.

That legibility has made highline stunts desirable properties for global brands active in the extreme sports sponsorship layer. Red Bull has historically used feats of this profile to generate sustained visual content — photographs and video sequences designed to circulate across social platforms under an event hashtag, accumulating impressions that serve both the athlete and the brand. The dynamic benefits the company most directly: the content infrastructure belongs to Red Bull, not the city or its taxpayers.

What cities receive in return is the subject of some debate. Warsaw, as the capital of Poland's largest economy and a city that has invested significantly in positioning itself as a Central European financial and cultural hub, could meaningfully argue that hosting a globally noticed stunt adds a data point to its cultural profile. Whether that profile translates into economic value — tourism, foreign investment, talent attraction — is difficult to isolate from the broader noise of competing city-marketing campaigns.

Warsaw's skyline as a backdrop

Poland's capital has undergone a significant transformation since the early 2000s. The skyline that now contains several towers above 150 metres did not exist in any meaningful form thirty years ago. The reconstruction period after 1989, and the subsequent commercial building boom of the 2000s and 2010s, produced a cluster of towers in the Śródmieście district that now functions as a shorthand for the city's ambitions.

Using that skyline as a performance stage carries an implicit argument: that Warsaw is a city large and confident enough to host a global spectacle, that its towers are not merely office blocks but landmarks with cultural meaning. That argument is legible whether or not the stunt succeeds. An aborted or cancelled attempt would still generate news — and the news, regardless of outcome, would mention Warsaw.

This framing places Warsaw in a category shared with cities like Toronto, Dubai, and Singapore, all of which have hosted similar urban highline stunts in recent years, typically in partnership with brands seeking exactly this kind of cultural integration with aspirational skylines. The shared logic is that the city and the brand co-produce a moment; the brand brings the athlete and the content machinery, and the city supplies the iconic architectural backdrop.

What this signals and what remains unresolved

The May 31 attempt, if it proceeds as announced, will arrive at a moment when cities are increasingly competing for visibility in a global attention economy that shows no signs of becoming less crowded. The infrastructure to stage these events is not complex. The willingness of building owners to grant access — when it exists — is the more binding constraint, and that willingness is itself a product of a city's openness to spectacle.

Whether Warsaw's municipal government, tower management companies, or emergency planning authorities were consulted prior to the May 28 announcement cannot be confirmed from the sources reviewed. The Telegram source that announced the event did not detail the permitting or coordination process. Whether any public safety considerations have been formally addressed remains unresolved in the public record.

What is clear is that the event will proceed if weather and safety conditions permit, and that Red Bull's content apparatus will be pointed at it regardless. Warsaw, for the duration of a morning or an afternoon in late May, will occupy a specific slice of the global extreme sports media ecosystem — a place it has not held before.

The question of whether that occupation is worth the effort is a matter for city planners and taxpayers rather than spectators. The spectacle itself is likely to be considerable.
