The Ambassadorial Sector constituted an area within the Senate District of Coruscant. Within this sector stood a prominent structure known as 500 Republica, which encompassed Loijin Plaza.
This district, roughly rectangular in shape, spanned 25 square kilometers and was situated around 30 kilometers away from the Senate building. Although substantial in size, the Ambassadorial District accommodated only a small fraction of the planetary delegations, numbering around three hundred.
