The Memorial Gymnasium was built shortly after World War II to honor Tilton students who had served and died for their country. In 1998, the building was completely renovated and rededicated as the Memorial Athletic and Recreational Center (MARC). In the building is a memorial honoring Tilton students who have died in battle, dating back to the Civil War era. The memorial also displays Stephen Holden Doane's ('66) Medal of Honor, which was given to the school by his family. The building contains two basketball courts, a climbing wall, a weight room, six locker rooms, a training room, and a student center including a snack bar called Rusty's Den. A 2008 addition has extended the social area of the MARC, adding more couches, a larger television set, a pool table, and a foosball table. The previous wrestling room moved to the second story of the MARC.
