Federal District 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 . Description . Under the Galactic Republic , the central government district was generally referred to as the Senate District or the Legislative District , the focal point of which was the Senate Building that served as the meeting place of the Galactic Senate . In front of the Senate was Senate Plaza , whose Avenue of the Core Founders bore statues dedicated to the founding members of the Republic . Located nearby was the Senate Office Building , where the Supreme Chancellor maintained a suite of offices , 500 Republica , a prestigious and exclusive residential tower where Sheev Palpatine maintained an apartment during his service as senator of Naboo , and the Jedi Temple , which served as the home of the Jedi Order . With the fall of the Republic and the establishment of the Galactic Empire , the Jedi Temple was converted into the Imperial Palace and the term " Federal District " became the primary appellation of the central government district . Informally , however , the Federal District was referred to by Coruscanti as the " Core of Coruscant " or " Core Square . " The area surrounding the former Jedi Temple became a focal point of the so - called " supreme triangle " of the newly - christened Imperial Palace , together with the Naval Intelligence headquarters and the COMPNOR arcology that housed the Central Offices of the Imperial Security Bureau . It was also within the Federal District that the Imperial Military constructed a combined headquarters for the Imperial Army and the Imperial Navy . The district was covered with towering skyscraper s and its skies were kept clear via weather control . History . In the days of the Republic , the term " Senate District " was synonymous with the business and power of the galactic government . The Clone Wars brought about great changes to the district , as it saw a massive build - up of new structures to house the increase in government agencies that were created in support of the Republic ' s war effort . In 21 BBY , the Senate District was the site of a terrorist bombing and a rampage by a freed Zillo Beast from the planet Malastare . During the execution of Order 66 , Imperial forces secured the Jedi Temple under the command of the newly - christended Sith Lord Darth Vader . The Dark Lord of the Sith Darth Sidious , publicly known as Galactic Emperor Sheev Palpatine , subsequently confiscated the Temple and refurbished the structure as the Imperial Palace , the seat of the Galactic Empire . Along with other government structures that were constructed around it , the palace became the focal point of the Federal District as part of the " supreme triangle . " After the death of Emperor Palpatine at the Battle of Endor in 4 ABY , the turning point of the Galactic Civil War between the Empire and the Alliance to Restore the Republic , under the direction of Grand Vizier Mas Amedda , the Imperial Security Bureau seized control of Coruscant in an effort to put down the revolution that had erupted on the planet . As the Empire was driven back across the galaxy by the New Republic , Amedda was placed under house arrest by order of Gallius Rax , the self - styled Counselor to the Empire , while Imperial forces continued to lose ground and struggled to hold onto the upper levels of the Federal District . With the defeat of the Imperial remnants at the Battle of Jakku , Amedda signed the Galactic Concordance , formally marking the surrender of the Galactic Empire and replacing it on Coruscant with a provisional government that was overseen by the New Republic .
