One of baseball's most famous ballparks was originally built for a Federal League team: Wrigley Field, the home of the Chicago Cubs, began its long life as Weeghman Park, the home of the Chicago Whales. Marc Okkonen, in his book on the Federal League, referred to Wrigley as a "silent monument" to the failed Federal League experiment. Otherwise, few visible remnants were left by the short-lived Federal League. The Baltimore entry sold their facility to the Baltimore Orioles of the International League, who renamed it Oriole Park and played there for nearly 30 years before it was destroyed by fire. The Newark ballpark was also used for minor league ball for a short time.
