Great American Ball Park was built by the architectural firms HOK Sport (now Populous) and GBBN at a cost of approximately US$290 million.

[15] The Reds set the lowest attendance record (not counting 2020) on April 17, 2023, at Great American Ballpark, due to the cold weather.

A sign bearing Nuxhall's traditional signoff phrase "rounding third and heading for home" is located on the third base side exterior of the park.

In honor of Crosley Field, the Cincinnati Reds' home park from 1912 to June 1970, a monument reminiscent of the park's infamous left field terrace was built on the main entrance plaza on Joe Nuxhall Way; statues of Crosley-era stars Nuxhall, catcher Ernie Lombardi, first baseman Ted Kluszewski, and outfielder Frank Robinson are depicted playing an imaginary baseball game.

In right center field, two smokestacks, reminiscent of the steamboats that were common on the Ohio River in the 19th and early 20th centuries, flash lights, emit flames and launch fireworks to incite or respond to the home team's efforts.

[19] A 50-foot-by-20-foot (15 x 6 m) Indiana limestone bas relief carving near the main entrance features a young baseball player looking up to the heroic figures of a batter, pitcher and fielder, all set against the background of many of Cincinnati's landmarks, including the riverfront and Union Terminal.

After the Trans-Lux company collapsed in 2008, the Reds paid $4 million to install a new, LED scoreboard and HD video screen from Daktronics in time for the 2009 season.

As a nod to Crosley Field, the Reds' home from 1912 to 1970, a monument was created in front of the main entrance to highlight the park's famous left-field terrace.

Bronze statues of Crosley-era stars Joe Nuxhall, Ernie Lombardi, Ted Kluszewski, and Frank Robinson (created by sculptor Tom Tsuchiya) are depicted playing in an imaginary ballgame.

Located on the west side of Great American Ball Park on Main Street, the Hall of Fame and Museum celebrate the Reds' past through galleries and extensive use of multimedia.

For the 2015 season, Great American Ball Park became the first MLB ballpark to feature a suite designed exclusively as a place for mothers to feed and care for their babies.

[24] Reds COO Phil Castellini, a father of 5, says he felt compelled to do his best to provide a worthwhile solution after stadium officials told him an increasing number of women were asking where they could nurse their children at the ballpark.

The BetMGM Sportsbook at Great American Ball Park is located in the Machine Room, and features three betting windows and 15 self-service kiosks, in addition to a full-service bar and food options.
