Jedi Trials Chamber The Jedi Trials Chamber was a large room that was located within the Coruscant Jedi Temple . Serving the Jedi Order as a place for potential Jedi to be administered the Jedi Trials , a specialized program could project simulacrums of various Jedi and Sith to challenge the skills of a Jedi . History . Erected within the Temple Ziggurat , this chamber was destroyed and rebuilt several times in the Temple ' s long history , seeing completion in 1000 BBY under the Galactic Republic . In use for nearly a millennia after , the Trials Chambers served several generations of Padawans as they attempted to successfully join the ranks of the Jedi Knights . Housing the largest Jedi academy in the galaxy during the last millennia of the Old Republic , the Council of First Knowledge saw the need for a permanent area in which they could administer the Jedi Trials effectively and efficiently . Within this specialized chamber , Padawans ready to face the Trials would face a set of tests that would try their skills and spirit by pitting them against simulacrums of the most fierce Jedi and Sith ever to travel the galaxy . While not all Trials were held in this chamber due to the number of students the Temple ' s academy produced and the different circumstances surrounding each apprentice ' s knighting , throughout the centuries , the Temple elevated several thousand Knights . At the end of the violent Clone Wars , the Republic which the Jedi had served for so long was dissolved and transformed into the Galactic Empire . The Temple was placed under martial law by decree of Order 66 . The 501st Legion of the Grand Army of the Republic , led by Darth Vader , stormed the Temple and executed its occupants , damaging the Temple in the process . The Temple ' s Trial Chamber escaped with only a few blaster - burns and toppled statues but was structurally sound . In 2 BBY , with a small contingent of stormtroopers still occupying the Temple , Darth Vader sent his secret apprentice , Starkiller , to the Temple in order to complete the Trial of Skill . Having passed through the stormtrooper - guarded entry hall , Starkiller made his way deep into the Temple where he located the Trials Chamber . Upon entering the room the old Trials Program activated and the simulacrum of Darth Desolous stalked out of the shadows and engaged the assassin in a duel . After an exhausting lightsaber fight , Starkiller used the Force to topple the statue of Emperor Palpatine which had been installed at the far end of the chamber . The Trial passed , Starkiller left the Temple with a new mission from his master . A few weeks after the duel in the chamber took place , the hall leading down to the chamber collapsed , leaving the room inaccessible . The Hall would stand in silence for several more decades , collecting dust and slowly crumbling . When Darth Sidious and Vader were slain , the Empire lost balance and was eventually ousted from Coruscant by the New Republic . During the Yuuzhan Vong War Coruscant was devastated by terraforming , causing the Temple to crumble and reveal parts of the foundation . When the Galactic Alliance reclaimed the world , Chief of State Cal Omas , ordered the Reconstruction Authority to rebuild the ancient edifice as a gift for the great sacrifices made by the reformed Order against the Yuuzhan Vong . While the structure was rebuilt using blueprints of the old building , it is unknown if the Trials Chamber was reconstructed or replaced . Layout and style . Located deep in the Temple Ziggurat , this high - ceiling chamber was constructed out of a dark stone and was dimly lit . Located off an ancient passage way , this doorless hall consisted of several stepped areas lined with stone and bronzium statues of Jedi Masters long dead . Within the architecture of the room , the Jedi Trials Program was stored , capable of constructed simulacrums of ancient warriors capable of dueling and injuring Padawans sent to defeat them . Upon the fall of the Order , this room was opened for touring by the Emperor , who would bring the elite of Coruscant inside to view the downfall of the Jedi . Within the Trials chamber , Palpatine had erected a massive statue of himself depicting his dominance over the Jedi .
