The Hall of Justice, or simply the Hall, is a fictional headquarters appearing in American comic books published by DC Comics. The Hall of Justice serves as a headquarters for the Justice League. It was first introduced in the Super Friends animated series on September 8, 1973, and it eventually appeared in comic book titles related to the Justice League, as well as video games and other media. The show was produced by Hanna-Barbera, a division of Cincinnati-based Taft Broadcasting. One of the animators, Al Gmuer, likely visited Cincinnati Union Terminal while attending meetings and confirmed that he was inspired by the terminal in designing the superhero headquarters. Union Terminal was also featured in the 1996 DC comic book series Terminal City. The Six Flags Magic Mountain: Justice League: Battle for Metropolis ride is a replica of the Hall of Justice, and the building initially housing the Hall of Heroes Superhero Museum in Elkhart, Indiana, was modeled after the Hall of Justice, though on a smaller scale. Design history In 1973, the American Broadcasting Company (ABC) acquired rights to the DC Comics characters and partnered with animation company Hanna-Barbera to adapt the Justice League of America comic book for television, changing the name to the Super Friends, and adapting various elements of the comics to be more family-friendly. The producers of the series "wanted a grand headquarters for their heroes". The task was assigned to Al Gmuer, background supervisor for Hanna-Barbera for more than 30 years, with a knowledge of architecture. Gmuer apparently modeled the fortress after the art deco Union Terminal in Cincinnati, Ohio, a train station turned museum. Gmuer "sketched out a building that almost resembled the finished product", and gave the sketch to the network, "where it was turned into the Union Terminal look-a-like that's known today". Like the Union Terminal, the facade of the Hall of Justice is a monumental semicircle, with a half-circle of windows divided vertically by mullions, and a horizontal marquee running the length of the beneath the windows. This is flanked by square towers, equal in height to the dome (unlike the much shorter flanking elements of the Union Terminal). Cincinnati was also where Hanna-Barbera's corporate parent of the time, Taft Broadcasting, happened to be based. Gmuer later commented of the animated Hall of Justice: "In the long run, I hated that building...The way it's designed, it was not easy to draw.
