THE NFL is littered with awe-inspiring stadiums where American football fans watch their heroes go to battle.
Many of them have undergone drastic facelifts over the last few decades, including the home of the current Super Bowl champions, the Philadelphia Eagles.
The Eagles play their football at the instantly recognisable Lincoln Financial Field, which will host the kick-off game for the 2025 NFL season.
The site, however, used to house a much bigger ground, which has since been forgotten about - the Philadelphia Municipal Stadium.
Municipal Stadium was an open-air ground which was incredibly built in the shape of a horseshoe.
The ground, which partially anchored the southern section of Broad Street, also had a track around the football field for athletics events to take place.
The iconic ground, which was built entirely out of brick, stone and concrete, opened in 1926 and was first occupied by the Philadelphia Quakers - the winners of the one and only season of the American Football League.
The Eagles first made the ground their home in 1933 before a four-year stint at Shibe Park from 1935 to 1939.
They returned in 1950 for one day in a match which would eventually lay the groundwork for the season kick-off game.
That game between the Eagles and the Cleveland Browns was attended by a whopping 71,237 fans, who saw the hosts ripped to shreds in a 35-10 rout.
Municipal Stadium also hosted 41 annual Army-Navy college football matches between 1939 and 1979.
The Roman-inspired stadium also held a gladiatorial-esque event in 1926.
A whopping 120,557 spectators crammed into the stadium to watch boxing legend Jack Dempsey lose his heavyweight title in a torrential rainstorm.
In 1957, another huge crowd gathered at the ground for a NASCAR Convertible race, which was won by Bob Welborn.
In 1964, the stadium was renamed the John F. Kennedy Stadium in memory of the assassinated former President, who was killed in Dallas a year earlier.
A number of sporting events and concerts were held at the stadium in the 1970s and '80s, although it started to become dilapidated.
And it was condemned in 1989 by former Mayor Wilson Goode after city inspectors deemed it to be a potential fire hazard, as well as structurally unsafe.
Renovations and repairs were discussed, but the proposals were swiftly rejected due to the astronomical costs.
That decision ultimately led to the iconic JFK Stadium being demolished in September 1992.
The Philadelphia Eagles kick off their pursuit of two-straight Super Bowl titles on September 9, hosting the Dallas Cowboys.
