Galactic City

Galactic City was the name of the planet-wide city of Coruscant. During the Galactic Republic, it was also known as Republic City or the City of Spires. During the Clone Wars the city was referred to as Triple Zero in military slang due to Coruscant's hyperspace code Zero Zero Zero (0,0,0). Galactic City was also called Imperial City (or, rarely, Coruscant City) under the Galactic Empire and New Republic City under the New Republic with the city remaining the same much in structure and style as millennia earlier. Although technically applying to all of Coruscant, in common usage its name seems to have referred to the Senate, Temple and Ambassadorial Districts—the areas of the planet which housed the Senate Building, the Jedi Temple, the Republic Executive Building, the Imperial Palace, and other main organs of the Republic government.

The only major physical change to the city was when the Yuuzhan Vong conquered the planet in 27 ABY and had its surface terraformed with vegetation from their home galaxy and then renamed it as Yuuzhan'tar.
