The Federal District, also called the Senate District or Legislative District and colloquially as the Core of Coruscant or Core Square, was the central government district on the planet Coruscant. It was the location of the Senate Building, the Avenue of the Core Founders, the Senate Office Building, and the Jedi Temple which, after the creation of the Galactic Empire, was rechristened as the Imperial Palace. Other notable locations included 500 Republica, the headquarters of the Naval Intelligence Agency, and the COMPNOR arcology, which contained the central offices of the Imperial Security Bureau.
