HAMILTON, Ohio (AP) — City officials in Ohio were present for a ceremonial groundbreaking on a planned sports complex that will be one of the largest in the world when it is completed in 2021.

Hamilton has committed $26 million of the $144 million it will take to transform the deserted Champion paper mill into the Spooky Nook Sports complex. Spooky Nook founder Sam Beiler says the mega complex could be used to host multiple types of events, from sports tournaments to weddings.

The company’s name comes from the Spooky Nook Road location of its first mega project in Lancaster County, Pennsylvania.

City officials say the complex will contain the Greater Cincinnati area’s second largest convention space once completed.
