The Universal Exposition of 1900 took place from 15 April until 12 November 1900. It celebrated the turn of the century and was by far the largest in scale of the Expositions; its sites included the Champ de Mars, Chaillot, the Grand Palais and the Petit Palais. Beside the Eiffel Tower, it featured the world's largest ferris wheel, the "Grande Roue de Paris", one hundred metres high, that could carry sixteen hundred passengers in forty cars. Inside the exhibit hall, Rudolph Diesel demonstrated his new engine, and one of the first escalators was on display. The Exposition coincided with the 1900 Paris Olympics, the first Olympic games held outside of Greece. The Exposition popularized a new artistic style, the Art nouveau, to the world. Two architectural legacies of the Exposition, the Grand Palais and Petit Palais, are still in place in the city. Though it was a great popular success, attracting an estimated forty-eight million visitors, the 1900 exposition lost money and was the last such exposition in Paris on such a grand scale.
