The exhibit is a collection of plaques that honor players and personnel who made significant contributions to the Philadelphia Phillies organization.

When Citizens Bank Park was completed in 2004, a single plaque listing all of the Athletics inductees was attached to a statue of Connie Mack located outside the west side of the stadium.

[6] However, on August 12, 2017, just ten days before the ceremony, the Phillies announced Rose would not be inducted amid recent statutory rape allegations.

[8] Along with the plaques, the new plaza features other aspects of Phillies history, including large replicas of the team's World Series trophies from 1980 and 2008, statues of its retired numbers, and banners commemorating the team's World Series titles, league pennants, division titles, and wild card berths.

[10] The next year, this followed with the induction of three members: owner and president Ruly Carpenter, general manager John Quinn, and third baseman Scott Rolen.

Although the present-day Oakland Athletics have retired no numbers for players from their Philadelphia years, all nine players for whom the Phillies have retired a number or honored a "P" have been inducted into the Wall of Fame: Robin Roberts (1978), Richie Ashburn (1979), Chuck Klein (1980), Grover Cleveland Alexander (1981), Jim Bunning (1984), Steve Carlton (1989), Mike Schmidt (1990), Dick Allen (1994) and Roy Halladay (2021).
