The Ferris wheel is a large-scale mechanical facility, shaped like a runner, and with a cockpit for passengers hung on the edge of the wheel. Passengers sit on the Ferris wheel and slowly turn upward, overlooking the surrounding scenery from a height.

The most common Ferris wheels can generally be found in amusement parks.

The earliest Ferris wheel was designed by American George Faris in 1893 for the Columbian Exposition in Chicago. Its purpose was to compete with the Eiffel Tower, built in Paris at the 1889 Exposition. The first Ferris wheel weighed 2,200 tons, could seat 2,160 people, and was as tall as a 26-story building.

Modern Ferris wheels are characterized by their height and beautiful appearance. In addition, many Ferris wheels are also equipped with various lighting and sound equipment, allowing visitors to enjoy a more spectacular landscape at night.
