Principal Park in Des Moines, IA, is the home of the Iowa Cubs, the Chicago Cubs' Triple-A International League farm team. The Iowa State Capitol is visible beyond the ballpark's outfield - but it is now visible to fewer fans in the stands.

MLB's 2021 Minor League Reorganization mandates a 36-foot tall "batter's eye" - a solidly dark-colored area of the centerfield wall, designed to keep batters from having to pick up a white baseball out of a white or light background. Principal's pre-existing 16-foot eye left left-handed batters vulnerable to glare from the capitol dome; the required increase alleviates that but also blocks the capitol from the view of about one in five seats. The I-Cubs' new eye debuted in their June 14, 2022, game - far earlier than originally projected. Less than a month later, though, a summer storm blew it apart. A temporary replacement went up in time for the next I-Cubs' home game, and a permanent one followed in 2023.

Its scoreboard is manual for score by innings and line score, one of eight in Professional Development League baseball.

The same-site, same-name replacement of Sec Taylor Stadium opened in 1992, keeping the name of the late Des Moines Register and Tribune sports editor until Principal Financial Group bought naming rights in 2004. As late as August 1991, contemporary media accounts referred to the upcoming project as a renovation,[1] but today's histories say the old Sec Taylor Field was "demolished" on September 10th of that year and replaced by a new park that opened 208 days later. It was designed by HOK Sport (now Populous).

A 2008 game was played to empty seats amid flooding evacuations because the I-Cubs and Nashville Sounds had no possible make-up dates remaining.

The original stadium, opened as Pioneer Park in 1947, had been renamed for Taylor in 1959.
