ArcelorMittal Orbit
The ArcelorMittal Orbit stands as Britain's tallest sculpture and one of London's most distinctive landmarks, rising 114.5 metres above Queen Elizabeth Olympic Park in Stratford. Conceived as a permanent legacy of the London 2012 Olympic and Paralympic Games, the structure was the result of a chance conversation in 2009 between London Mayor Boris Johnson and steel magnate Lakshmi Mittal. Johnson reportedly sketched his vision for an iconic Olympic structure on a napkin during a meeting, and Mittal, whose company ArcelorMittal is the world's leading steel manufacturer, agreed to provide the majority of the £19.1 million funding. The sculpture was designed by artist Anish Kapoor in collaboration with structural designer Cecil Balmond of Arup, bringing together artistic vision and engineering expertise to create something unprecedented in scale and form.
The Orbit's design draws inspiration from the interlocking loops of the Olympic rings, though its twisted, looping red lattice structure defies simple categorization. Standing twice the height of Nelson's Column, the sculpture contains 1,400 tonnes of steel arranged in a deliberately chaotic, tumbling arrangement of intersecting tubes and spirals. Kapoor described his intention as creating "an image of a tower, but not a tower," something that appears both stable and unstable simultaneously. The structure's distinctive Teesside red colour comes from the paint used to protect the steel, and the entire framework appears to twist and contort as visitors walk around its base, offering constantly changing perspectives. The spiral lattice creates numerous unexpected geometries and spatial relationships, with some sections appearing to defy gravity as they cantilever outward from the central core.
The observation platforms positioned at two levels provide panoramic views across London, extending up to 20 miles on clear days. Visitors can see across the entire Olympic Park below, with views stretching to landmarks including Canary Wharf, the City of London, Wembley Stadium, and on exceptionally clear days, even as far as the countryside beyond Greater London. The viewing experience combines the thrill of height with an unusual perspective filtered through the sculpture's red steel framework, which frames and fragments the cityscape in unexpected ways. The enclosed platform at the top offers protection from the elements while maintaining 360-degree visibility through extensive glazing.
In 2016, the Orbit underwent a significant transformation with the addition of the world's longest and tallest tunnel slide, designed by German artist Carsten Höller. The slide, measuring 178 metres in length, spirals around the outside of the sculpture, taking riders on a 40-second descent through light and darkness, complete with twists, turns, and a transparent section offering fleeting glimpses of the park far below. This addition transformed the purely observational experience into something more visceral and participatory, adding an element of contemporary artistic intervention that complements Kapoor's original vision while attracting a broader audience seeking thrills alongside cultural enrichment.
The structure serves multiple functions within the broader context of Queen Elizabeth Olympic Park's regeneration. Beyond its role as visitor attraction, the Orbit has become an instantly recognizable symbol of East London's transformation, appearing in countless photographs and serving as a wayfinding landmark visible from across the surrounding boroughs. The sculpture anchors the southern end of the Olympic Park, creating a focal point that draws visitors deeper into the regenerated landscape. Its presence has contributed to Stratford's emergence as a cultural destination, complementing the nearby London Stadium, the London Aquatics Centre, and the growing arts and entertainment offerings in the area.
Visitors access the observation platforms via a lift that ascends through the center of the sculpture, though the adventurous can opt to climb the 455 steps on foot. The ascent on foot offers an entirely different experience, with the staircase winding through the sculpture's complex interior geometry, revealing the intricate engineering and construction techniques up close. At various points during the climb, small windows offer previews of the views to come, building anticipation for the summit experience. The descent can be made via the same routes or, for those seeking additional excitement, via the tunnel slide, which requires a separate ticket and adherence to height and health restrictions.
The Orbit has generated considerable debate since its conception, with critics and supporters offering sharply contrasting views. Some architectural commentators have praised its bold ambition and the way it challenges conventional notions of public sculpture, while others have criticized it as an expensive folly that lacks aesthetic coherence. Regardless of these debates, the structure has achieved its primary goal of creating a lasting Olympic legacy that attracts visitors and generates conversation. The building has won several awards, including the 2012 Structural Awards Prize for Arts or Entertainment Structures from the Institution of Structural Engineers, recognizing the remarkable engineering achievement required to realize Kapoor and Balmond's vision.
The sculpture's location in Stratford, East London, is itself significant, representing the Olympic Park's role in regenerating what was previously one of the capital's most economically challenged areas. The Orbit stands on what was once industrial land, transformed into the Olympic Park for 2012 and subsequently developed into a mixed-use destination combining parkland, residential areas, educational institutions, and cultural venues. The choice to locate such a prominent artwork in East London, rather than in the traditionally more tourist-oriented areas of central London, represented a deliberate attempt to redistribute cultural capital and visitor attention across the city.
The Orbit remains open year-round, with timed entry tickets available for advance booking online or purchase on the day, subject to availability. The venue offers various ticket options, including combined tickets for both the viewing platforms and the slide experience. Educational programs and special events are regularly hosted, including abseil experiences for charity and occasional artistic installations that utilize the unique space. The structure is accessible via Stratford station, which serves as a major transport hub with London Underground, Overground, DLR, and National Rail services, making it one of the most easily accessible points of interest in London. The immediate surroundings include extensive parkland, waterways, and public art, allowing visitors to combine their Orbit experience with broader exploration of Queen Elizabeth Olympic Park.
