Hanna City functioned as the planet Chandrila's capital. During the New Republic Era, this city stood as a symbol for the New Republic, and it briefly held the position of its capital.
As the capital of Chandrila, Hanna City was a sprawling city. Constructed directly on the edge of the vast Silver Sea, the city's white, cliff-like structures, along with soaring spires and domed buildings, directly bordered the pebbled beaches. The ocean was vital to the city's commercial fishing sector, with a fishery and docks situated in proximity to Barbican Road. The city streets were frequently alive with bustling crowds. Speeder traffic was also a common sight near the main docking station around midday. To manage the large population, Hanna City had hundreds of landing platforms that were controlled by Chandrila tower control. One of the larger buildings in the city was the New Republic Defense Fleet headquarters, a shining symbol of the New Republic.
The area outside Hanna City was characterized by scenic misty forests and windswept meadows, which encircled the city and could be seen from certain taller buildings. Other seaside locations were also present, such as Junari Point, located a few kilometers from the city.
In 5 BBY, its governor was acquainted with Perrin Fertha, having served in the same regiment as him. That year, the governor was present at a dinner party hosted by Fertha at the Chandrilan Embassy. The city housed the Galactic Senate of the New Republic, as Mon Mothma chose her homeworld of Chandrila to be the Republic's capital following the Battle of Endor. In the early days of the new Senate, the city circle in Hanna City was the site of an art installation featuring stormtrooper helmets adorned with Rebel Alliance symbols, starbursts, and a variety of colors. The HoloNews network Queen of the Core Network's inaugural broadcast covered the celebrations taking place in Hanna City.
