Ferris wheel

A Ferris wheel (also known as an observation wheel or big wheel) is a nonbuilding structure, consisting of a rotating upright wheel with passenger cars (sometimes referred to as gondolas or capsules) attached to the rim.

The original Ferris Wheel was designed and constructed by George Washington Gale Ferris, Jr. as a landmark for the 1893 World's Columbian Exposition in Chicago. The term Ferris wheel later came to be used generically for all such structures.

Sometimes also referred to as the Chicago Wheel, opened to the public on June 21, 1893, at the World's Columbian Exposition in Chicago, Illinois. Intended to rival the 324-metre (1,060 ft) Eiffel Tower, the centerpiece of the 1889 Paris Exposition, it was the Columbian Exposition's largest attraction, with a height of 80.4 metres (264 ft).
