After over a thousand years of fund - raising and rebuilding , the Galactic Senate was finally able to allot enough tax money to finish the Council Spires by 1000 BBY . At the conclusion of the Clone Wars Dark Lord of the Sith Darth Sidious , known as Supreme Chancellor Palpatine to all but his closest advisers , ordered the destruction of the Jedi Order through a military operation known as . Darth Vader led the 501st Legion into the Temple and began to systematically slaughter its occupants . Following the abandonment of the Temple the chamber saw no use as the Council was dissolved . The Temple would survive for much of the Galactic Civil War , the Council Chamber leering over the surface of Coruscant for years . The ancient edifice was even re - inhabited briefly , as members of the new Jedi Order searched the destroyed hall for any information on the teachings of the old Order . It wasn ' t until several years later that the five towers of the Temple collapsed , the Council chamber completely destroyed . The new Order would clear the rubble away and erect a small praxeum in their place on the roof of the Ziggurat ; though this too would be lost during the Yuuzhan Vong War . Reconstruction . Following the retaking of Coruscant by the Galactic Alliance , Chief of State Cal Omas donated a new Temple to the Order in recognition of the Jedi ' s efforts during the war . Using blueprints salvaged from the old Archives the Reconstruction Authority erected the new Temple to near - exact specifications ; though a new transparisteel pyramid concealed the restored Council towers . Layout . Located at the peak of the southeast tower of the Temple , this circular chamber granted its occupants a rare glimpse of Coruscant . Circular in shape and accessed by a single turbolift , the room was lined with high arching windows , and a ring of five cushioned chairs for the members of the Council . Each of the stone seats was equipped with a holoprojector that could be used when a Council member was attending the meeting from a distant world . Erected atop the Council Spire of the Temple , the chamber was ringed by a small corridor set between the inner and outer sets of transparisteel windows which granted a panoramic view of the cityscape . The turbolift was specially crafted with Force - inspired dynamics in order to accommodate Jedi of different species and size . Incorporated into the five pillars spread around the room were the supports and wiring for the reception / transmission antennas that crowned the spire . These antennas were responsible for feeding data to Jedi Command .
