Millennium Force is a steel roller coaster built by Intamin at Cedar Point amusement park in Sandusky, Ohio, United States. It was the fourteenth roller coaster to be built at the park since the Blue Streak opened in 1964. Upon completion in 2000, Millennium broke six world records and was the world's first Giga Coaster, a roller coaster that exceeds 300 feet (91 m) in height. It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year.
