When it began operating, Technocosmos was the World's tallest extant Ferris wheel. At that time, the tallest Ferris wheel ever built was the Grande Roue de Paris (built for the 1900 Exposition Universelle in France) which was demolished in 1920. In 1989 the Cosmo Clock 21 opened for business in Yokohama and succeeded both Technocosmos as tallest extant Ferris wheel and Grande Roue de Paris as tallest Ferris wheel ever built.
