Ain Dubai (previously named the Dubai Eye or Dubai-I at Bluewaters Island in the United Arab Emirates, is the world’s tallest and largest observation wheel, with a height of over 250 m (820 ft) and was announced in February 2013. Hyundai Engineering & Construction and Starneth Engineering were appointed as the primary design and construction contractors., together with KCI the engineers who designed and engineered the complete wheel structure including the installation engineering. Construction began in May 2015, anticipating completion in early to mid-2019. Further delays pushed the target opening to 20 October 2020, to coincide with Expo 2020, but this itself was postponed due to the COVID-19 pandemic. The wheel opened a year later on 21 October 2021.
Ain Dubai is 82.4 m (270 ft) taller than the previous world's tallest observation wheel, the 167.6 m (550 ft) High Roller, which opened in Las Vegas in March 2014. The wheel carries up to 1,750 passengers in 48 cabins and provides views of Dubai Marina and landmarks such as Burj Al Arab, Palm Jumeirah, and Burj Khalifa.
