ArcelorMittal Orbit: London's Iconic Olympic Sculpture and Thrilling Observation Tower

A Monumental Legacy of the 2012 Olympic Games

The ArcelorMittal Orbit stands as a bold and imaginative symbol of London’s hosting of the 2012 Summer Olympic and Paralympic Games. Conceived as a permanent legacy, it was designed by renowned sculptor Anish Kapoor and structural engineer Cecil Balmond. Completed in 2012 and opened to the public in 2014, this 114.5-metre (376-foot) tall structure is the tallest sculpture in the UK and a centerpiece of the Queen Elizabeth Olympic Park in Stratford. Its creation was driven by the ambition to create an iconic landmark comparable to the Eiffel Tower, yet uniquely British in its artistic and engineering expression.

Striking Design and Engineering Marvel

The ArcelorMittal Orbit’s design is a complex lattice of looping red steel tubes, twisting asymmetrically to create a dynamic and sculptural form. The structure contains 366 star-shaped nodes and is held together by 35,000 bolts, with 19,000 litres of distinctive red paint giving it its vibrant color. Approximately 2,000 tonnes of steel were used, with 60% recycled, reflecting a commitment to sustainability. The sculpture’s shape widens at the base, narrows in the middle, and expands again near the top, stabilized by diagonal steel connectors and a tuned mass damper pendulum weighing 40 tonnes to ensure steadiness against wind and movement.

Observation Platforms with Sweeping Views

Visitors ascend the Orbit via one of two lifts to reach two indoor viewing platforms, each accommodating up to 150 people. From these vantage points, the panoramic views span the entire 250-acre Olympic Park and extend across London’s skyline, including landmarks such as the London Stadium and the Aquatics Centre. For those seeking a more active experience, a spiral staircase with 455 steps winds through the sculpture, offering a unique perspective on the structure’s intricate design.

Helix: The World’s Longest and Tallest Tunnel Slide

In 2016, the ArcelorMittal Orbit became home to Helix, a thrilling 178-metre-long tunnel slide that spirals 12 times around the sculpture, descending 76 metres. This slide holds the record as the world’s longest and tallest tunnel slide, reaching speeds up to 15 mph. Visitors take a lift to the top, don protective gear, and slide down on mats, experiencing the structure and the park from exhilarating new angles. The slide adds an adventurous dimension to the Orbit, attracting thrill-seekers alongside art and architecture enthusiasts.

Location and Surroundings

Situated in the southern part of Queen Elizabeth Olympic Park, the Orbit sits between the London Stadium and the Aquatics Centre, making it a focal point within the park’s vibrant landscape. The park itself is a rejuvenated area of East London, transformed by the Olympics into a public space featuring sports venues, gardens, playgrounds, and cultural attractions. The Orbit’s visibility from all parts of the park and its striking silhouette make it a landmark for visitors and locals alike.

Engineering Challenges and Cultural Impact

Building the Orbit was a feat of engineering and artistic collaboration. Each steel piece was uniquely shaped, requiring precise manufacturing and assembly. The project involved a small, skilled team and innovative solutions to stabilize the asymmetrical form. Beyond its physical presence, the Orbit symbolizes regeneration and creativity in East London, blending public art with interactive experience. It continues to be a vibrant part of London’s cultural fabric, celebrating the city’s Olympic heritage while offering unforgettable views and adventures.
