Three Rivers Stadium opened in 1970 as the new home of the National Football League's Pittsburgh Steelers, as well as Major League Baseball's Pittsburgh Pirates. Similar to other so-called cookie-cutter stadiums of the era (The Vet in Philadelphia, Riverfront in Cincinnati, etc.), Three Rivers closed in 2000. At the time the stadium opened, the Pirates were consistently in the postseason, winning the World Series in 1971. The stadium was often referred to as "The House That Clemente Built" after the Pirate's legendary superstar Roberto Clemente.
