The ancient Tower that houses the chambers of the High Council has stood the test of time since the construction of the ziggurat on Coruscant. The masonry of the spire is supported by a highly-tensile substance known as magnate, which aids in the support of the thin frame of the Tower. Also, the permem incorporated into the Council Chamber’s windows supports in maintaining a constant gravity balance, along with keeping the artificial air supply operational at such altitude. The turbolift that lead to the Council Chamber was crafted by great Jedi architects, who incorporated Force-inspired, internal dynamics, which allows for the different sizes and shapes of the Order’s members to ascend the narrow spire.
At the base of the tower is the Mess Hall, where Masters and Younglings alike take their meals. It is simple fare, but healthy and nourishing for all the various species present, and the kitchen works nonstop considering the different schedules of everyone as well as the amount of people served - peak hours tend to be Early Morning and Early Evening.
The halls of the tower tends to be lined with statues of Jedi Masters of old, and there are many bridges that crosses the central shaft of the tower where they all encircle around the large stone statue of a nameless Jedi that is kept suspended with repulsor-pads.
Fifteen stories below the Council Chamber there's a hangar equipped with garages below the floor and an aircraft control station in the ceiling. A retractable landing platform could be extended from the chamber's mouth out over the Temple Ziggurat for easy launches from the hangar. The room is staffed by mechanics and astromech droids, and is a popular place for Jedi of all ages to pass the time with repairs or tinkering with their own devices.
The residences of the High Council members are also located in the Tower, providing them more private accommodations and immediate access to the Council Chamber. Located above the atrium to the Tower, the chambers are typically small and hexagonal, with meditation cushions placed in the center of the room.
