An icon of Vienna, the Giant Ferris Wheel (also known as the Wiener Riesenrad) offers visitors great views of the city. Built in 1897, and the tallest ferris wheel in the world from 1920 to 1985, the Giant Ferris Wheel is a unique piece of history as well as a fun attraction! Lines can get long, especially in summer, so it’s recommended that you book skip-the-line tickets in advance for the best experience.
