Construction of the observation wheel took more than a year and a half to complete. In the process over 1700 tonnes of steel were used for the structure and more than 3000 tonnes of concrete were used for the foundations.
The futuristic looking capsules, accommodating up to 25 passengers, were transported all the way from France by train through the chunnel. Each egg-shaped capsule is 8 meters long and weighs 500kg. The 25 meter (82 ft) long spindle was built in the Czech Republic. The rim has a diameter of 122m (400ft), about 200 times the size of a bicycle wheel. 80 Spokes connect the rim with the spindle.
