Banshee is an inverted roller coaster located at Kings Island amusement park in Mason, Ohio. Designed and built by Bolliger & Mabillard, it was the biggest investment in park history at the time, costing $24 million to construct. With 4,124 feet (1,257 m) of track, Banshee opened to the public on April 18, 2014, as the longest inverted roller coaster in the world. The ride also became the third fastest inverted coaster at 68 miles per hour (109 km/h), matched by Steel Venom at Valleyfair in Shakopee, Minnesota. It was also well-received, ranking every year in the top 50 of Amusement Today's Golden Ticket Awards since its opening.
