Ain Dubai (World's Largest Ferris Wheel)

Ain Dubai is the world's largest Ferris wheel at 250 metres, dwarfing the London Eye by 100 metres and the High Roller Las Vegas by 10 metres. Its 48 air-conditioned cabins accommodate up to 1,750 passengers per rotation, and the structure required 9,000 tonnes of steel to complete, making it one of the most technically challenging rotating builds ever engineered.
