The stadium officially opened in 1960 as part of a new athletics area at the university and replaced the original
Memorial Stadium built in 1925 (a 20,000-seat stadium located on 10th Street in Indiana University's Arboretum). The current Memorial Stadium has been renovated or updated multiple times since the original construction. Improvements include the replacement of the original wooden seats with aluminum bleachers, installation of sound and lighting systems, and major structural overhauls. In 2019, the $8.5 million Terry Tallen Indiana Football Complex opened, after J.C. Ripberger Construction Corp was able to finish the project in only 6 months, including an expanded and renovated locker room area, training room and sports lounge, to allow players to get acquainted with video games on 98" televisions. is beyond the east stand. In September 2006, Indiana University announced plans to expand Memorial Stadium and enclose the north end zone. Demolition of the North End Zone bleachers took place in January 2007. This left capacity for the 2007 and 2008 seasons at 49,225. The expansion provides additional space for classrooms, a weight/training room, a Hall of Fame, and expanded seating for football, raising the stadium's
seating capacity to 52,692. Indiana Athletic Director
Fred Glass announced in July 2009 $3 million of additional renovations to the stadium for the 2009 season, including a new "retro" North End Zone scoreboard, a "Knothole Park" kids area in the south end zone, upgrades to the press box, repainting walkways, renovated concession stands, additional ticket booths, and new fencing around the stadium. A HD scoreboard from
Daktronics was added to the South End Zone for the 2010 season (which was the 29th largest collegiate scoreboard in the country), along with a state-of-the-art sound system. Indiana University Athletic Director Fred Glass announced on October 9, 2014, a planned project to enclose the south end of Memorial Stadium at an estimated cost of $10 million. The project included: a new rehabilitation and treatment facility for athletes, additional academic and life skills support facilities, a "multi-use" outdoor terrace on the roof of the structure, an entry plaza and green space at the south end of the stadium. The project was confirmed in March 2016, and was completed for the 2018 season. The total cost was $53 million. A new video board was installed in the North End Zone for the 2017 season, with a video board installed prior to the 2018 season, in the completed south end zone. On August 21, 2025, naming rights to the playing surface inside Memorial Stadium were sold to Merchants Bank.

Pacific Theater during
World War II, taking part in the invasion of the
Gilbert Islands,

Hep's Rock In 2005 head football coach
Terry Hoeppner had a southern Indiana
limestone boulder, nicknamed "The Rock", installed in the north end zone as a new campus tradition. This limestone boulder was found prior to Hoeppner's first season at IU in the practice field. It was removed, put on a granite slab and moved to the stadium. The Hoosiers and coach Hoeppner walked out and touched the Rock before running onto the field at every home game during Hoeppner's time as head coach. Terry Hoeppner died of brain cancer on June 19, 2007, and The Rock (renamed "Hep's Rock" during a ceremony with the Hoeppner family on November 6, 2010) now serves as motivation for the team as well as a tribute to Hoeppner's influence on the football program. The Rock was relocated to the East Concourse of Memorial Stadium before the 2024 season. == Playing surface ==
