The Jedi Grand Academy on Ossus was a towering stone structure erected by the Jedi Order to serve as their primary praxeum following the conclusion of the Clone Wars. Consisting of four above-ground ziggurat buildings and a massive underground facility, the Academy served as the training grounds for all Initiates within the Order until the time they were selected as Padawans. The Grand Academy campus was home to the Acolyte Academy which was housed within its eastern ziggurat structure. The Academy was led by an administrative Council made up of the heads of the primary departments and the Headmaster.
