The first Marshalltown High School was located north of downtown Marshalltown on Grant Street before moving to the present Miller Middle School. In 1965, the present Marshalltown High School building opened and has experienced minor additions including a library, weightroom, auditorium and classroom wings.
The Marshalltown High School athletics facilities include both outdoor and indoor sports accommodations. The outdoor facilities include baseball, football, soccer and softball fields, as well as a track. The indoor facilities include a swimming pool, and a gymnasium, known as the "Roundhouse", which has accommodations for basketball, volleyball, wrestling, and track. All areas are served by concessions, restrooms, parking and men's and women's locker rooms.
The Roundhouse was renovated in 2015 to include additional sports lockerrooms and the wooden bleachers were replaced with ADA-approved plastic bleachers. The MHS swimming pool area was also renovated to include windows to be able to view from the hallway and additional pool deck space.
