One CorSec Plaza, also known as the CorSec Headquarters, was a building located within CorSec Plaza in Coronet City on the world of Corellia. It was the headquarters of the Corellian Security Force.
In 3640 BBY, the CorSec Headquarters was attacked by a bounty hunter and the Sith Empire during the Battle of Corellia of the Galactic War. The bounty hunter captured CorSec Commissioner Jonah Carter.
Ex-CorSec agent Corran Horn, during his training at the Jedi Praxeum on Yavin 4, once told Luke Skywalker that he could have marched Bossk, the bounty hunter who had killed his father into One CorSec Plaza, pull out a blaster, shoot him in the head in front of hundreds of witnesses, and that everyone present would have sworn that the Trandoshan was "resisting arrest" and was a danger to those around him.
