The Hall appeared in the very first episode of the Super Friends series, which premiered on September 8, 1973. It was originally drawn by Al Gmuer, background supervisor for Hanna-Barbera for more than 30 years. Gmuer modeled the fortress after the art deco Union Terminal in Cincinnati, Ohio, a train station turned museum.
The Hall, located in Metropolis, serves as the central meeting point for the Super Friends. The Hall contains the Trouble Alert, a computerized monitoring station that would warn the heroes of a new threat. The Hall also houses a giant computer that the Super Friends use to analyze clues. By the mid-1980s, The Hall of Justice had a major remodel, at the same time the Super Friends changed their superhero team name to the "Super Powers Team."
In the episode "Universe of Evil", the evil Super Enemies from a parallel universe meet in a 'Hall of Evil'. It was identical in appearance to the Hall of Justice, with the addition of a gargoyle-style head above the front entrance.
