Chancellor Palpatine Commercial Nexus
From Wookieepedia, the Star Wars wiki.
The Chancellor Palpatine Commercial Nexus was a large spaceport on Coruscant built during, and named after, the chancellorship of Palpatine. It was connected to the Chancellor Palpatine Spaceport, and the combined complex dwarfed all other spaceports on Coruscant.
After the end of the Clone Wars, it was presumably renamed Emperor Palpatine Commercial Nexus.
