T-20: Turner Field (Atlanta Braves)
Turner Field is seeing its last year in 2016, being replaced by Sun Trust Park, which is expected in 2017. After just 19 years at The Ted, the Braves are leaving it despite this being a very good-looking ballpark. Its simple design is very well constructed.
The Ted was originally built for the 1996 Olympic Games, and the Braves moved in right after in 1997. It has hosted one World Series, one All-Star Game, and the first Wild Card Game in MLB history.
