American Family Field

American Family Field, known as Miller Park until 2020, is a retractable roofstadium in Milwaukee, Wisconsin. Located southwest of the intersection of Interstate 94 and Brewers Boulevard, it is the ballpark of Major League Baseball's Milwaukee Brewers. It opened in 2001 under the name Miller Park as a replacement for Milwaukee County Stadium.

American Family Field features North America's only fan-shaped convertible roof, which can open and close in less than 10 minutes. Large panes of glass allow natural grass to grow, augmented with heat lamp structures wheeled out across the field during the off-season.

The stadium opened in 2001 at a cost of $392 million. Between 1996 and 2020, taxpayers paid $609 million for the construction costs through higher sales taxes. In 2023, Wisconsin lawmakers entered into an agreement with the Milwaukee Brewers to spend nearly half a billion dollars of public funds on stadium renovations.
