Opened in April 2014, the ArcelorMittal Orbit, at 375 feet the tallest sculpture in the UK, is located in Queen Elizabeth Olympic Park (Stratford London; phone +44 0 333 800 8099), a 10-minute walk from London’s Stratford Tube station.
The tower’s unique design includes a complex structure resembling a roller-coaster track wrapping around it, and from either of two observation decks within it (£15, near $21), visitors can take in views of the adjacent Olympic stadium and the skyline of London.
