Riverfront Stadium, also known as Cinergy Field from 1996 to 2002, was a multi-purpose stadium in Cincinnati, Ohio. It was the home of the Cincinnati Reds of Major League Baseball (MLB) from 1970 through 2002 and the Cincinnati Bengals of the National Football League (NFL) from 1970 to 1999. Located on the Ohio River in downtown Cincinnati, the stadium was best known as the home of the "Big Red Machine", as the Reds were often called in the 1970s.
Construction began on February 1, 1968, and was completed at a cost of less than $50 million. Riverfront's grand opening was held on June 30, 1970, an 8–2 Reds loss to the Atlanta Braves.
