The original building was designed by architect Frank Shaver Allen in the "Collegiate Gothic" featuring arches, castellated walls, and towers.

Many archived items are kept in a vault; the display includes the original Steelman sculpture and conceptual models of it from the 1933 Chicago World's Fair.

The Steelman was sculpted by Louise Lentz Woodruff and is positioned with its hands behind a male and female, symbolizing technology advancing humans.

It is surrounded by the original relief panels representing the basic sciences: astronomy, mathematics, physics, chemistry, botany, zoology, medicine, and geology.

The new structure, designed by Wight & Co., features a three-story glass curtainwall facade that leads a student center and cafeteria that can seat up to 600 people for events.

The program is a member of the Southwest Prairie Conference (SWPC) and the Illinois High School Association (IHSA).

The athletic department sponsors interscholastic teams for young men and women in basketball, bowling, cross country, golf, soccer, swimming and diving, tennis, track and field, and volleyball.

McAllister, a manual arts instructor who played the cornet, was asked to organize a band for Joliet Township High School.

Mr. McAllister, who grew up on a farm in Jackson Township, bought a cornet at age 14 with profits he earned from selling his pig at the Will County Fair.

The band played for draftees, and was known as "the minute men" because they were always ready - day or night to perform for soldiers traveling through Joliet.
