Riverfront Stadium (1970–1995), later known as Cinergy Field (1996–2002), was the home of the Cincinnati Reds National League baseball team and the Cincinnati Bengals National Football League team. 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. On June 30, 1970, the Reds hosted the Atlanta Braves in their grand opening, with Hank Aaron hitting the first ever home run at Riverfront. Two weeks later on July 14, 1970, Riverfront hosted the 1970 Major League Baseball All-Star Game.
