Granite City was a city on earth during and after the First Robotech War. During the Malcontent Uprisings, a bunch of Zentraedi attacked. Jack Archer and Rick Hunter held them off and Jack brought Lynn Minmei to the Concert Hall for safekeeping. Jack and Rick neutralized the Malcontents attacking the Concert hall just as reinforcements arrived. They then left and Minmei performed a concert afterward. (Robotech: Battlecry : Road to Ruin)
