signage prior to the 2022 season. Between the exterior perimeter wall and interior of the stadium is the "Great Hall", a large concourse that runs between Gates 4 and 6. With seven-story ceilings, the Great Hall features more than of retail space and is lined with 20 banners of past and present Yankees superstars. The Great Hall features a LED (light-emitting diode) ribbon display as well as a 25' by 36' LED video display above the entrance to the ballpark from Daktronics, a company in Brookings, South Dakota. Monument Park, which features the Yankees' retired numbers, as well as monuments and plaques dedicated to distinguished Yankees, has been moved from its location beyond the left field fences in the original Yankee Stadium to its new location beyond the center field fences at the new facility. Monument Park is now situated under the sports bar; black shades cover the monuments on the back wall during games to prevent interference with the vision of the batter. The new location of the monuments is meant to mirror their original placement in center field at the original pre-renovation Yankee Stadium, albeit when they were on the playing field. The transfer of Monument Park from the old stadium to the new stadium began on November 10, 2008. The first monuments were put in place on February 23, 2009. Yankees pitcher Mariano Rivera requested that the Yankees reposition the team's bullpen, as well as add a door to connect the Yankees' bullpen to Monument Park, in order to allow access to it by Yankee relievers. The organization complied with his request.

Overall, the fences measure to left field, to left-center field, to center field, to right-center field, and to right field. At the old Yankee Stadium, the right field wall curved from the right-field corner to straightaway center, while at the new ballpark the fence takes a sharp, almost entirely straight angle. This results in a difference at certain points between the right field markers of as much as . The dimensions in left field are substantially the same
