The entrance into the Principia was through a monumental triumphal arch, with three passageways.
There were 14 rooms displayed on each side and they provided storage room for the weaponry. The rooms flanking the entrance were used as offices, as well as storage rooms for the amphorae containing import oil.
A basilica was located in the western part of the Principia. The entire complex closed off in the west with a suite of rooms. The fortress shrine and repository of the legionary standards stood in the middle of the Principia.
