A shiny steel and glass, doughnut-shaped viewing platform rose up against a slender pole on the seafront of the English town of Brighton, yesterday afternoon, thus officially opening the world’s thinnest observation tower. Dubbed the “vertical pier”, the British Airways i360 or simply the i360, stands 162 meters tall but is just 3.8 meters wide. The viewing platform, which also functions as the elevator, takes 200 passengers at a time on a slow ride up to the top of the tower, from where they can have unobstructed views of the entire city and the English channel for miles. This makes the i360 the world’s tallest moving observation tower. It is also the tallest structure in Sussex.
