Bank of America Stadium has many unique external features. Aspects of the stadium's architecture, such as the three huge main entrances, incorporate the team's colors of black, process blue and silver. Arches that connect column supports on the upper deck resemble the shape of half a football, while several acres of numerous trees and landscaping surround the building. The stadium's architecture and design has been compared to that of the Los Angeles Memorial Coliseum and Soldier Field, among others. It's also received mentions for externally resembling "a fortress" instead of a stadium.

Each of the stadium's entrances are flanked on both sides by two larger-than-life bronze panther statues, something unique throughout the entire NFL. These six statues are all named "Indomitable Spirit" and were installed in 1996. Each one depicts a crouching, snarling panther with green eyes; they are the largest sculptures ever commissioned in the United States. The names of the team's original PSL owners are engraved into each statue's base.

Another striking feature the stadium contains are its six light domes. These are found on top of the main entrances, two per entrance, and sit over a hundred feet in the air. Originally, they simply glowed the Panthers' unique 'process blue' every night. As the seasons wore on, the emitted light became less and less impressive and the domes started showing their age. During the 2014 renovations, the domes were rebuilt with LED systems. They can now be seen again projecting process blue nightly in various ways not possible with the original technology.

Additionally, two people in the Panthers Hall of Honor, former team executive Mike McCormack and former Panthers linebacker and assistant coach Sam Mills, are honored with life-sized bronze statues outside the stadium. Before the 2014 renovations, the names of the hall of honor inductees were placed where the upper ribbon board now resides. These names were subsequently repainted onto the top rear wall behind the last row of seats, then replaced by signs in 2019. Additionally, three marble copies of a quote about the stadium from team founder Jerry Richardson were placed near the stadium's entrances in 2014. Due to renovations, these quotes were later displayed in the lower concourse entrances. The quotes are also engraved on benches outside the stadium.

In 2016, a statue of Richardson was added in front of the stadium's north gate in celebration of his 80th birthday. The statue stands nearly 13 ft (3.96 m) tall and features larger than life sculptures of Richardson flanked on both sides by two panthers. One panther stands on its hind legs, claws bared, while the other crouches. All three sculptures have the same bronze color and both panthers have the green eyes of and physically resemble the "Indomitable Spirit" statues. In June 2020, the statue was removed, with the team citing potential safety concerns due to protests going on at the time.
