Jan gwa city plaza was a public square situated within Jan-gwa city, nestled in a valley on the planet of Naboo. In the year 21 BBY, the bounty hunter known as Cad Bane made an attempt to abduct the Gungan youngster Roo-Roo Page, who resided in a dwelling adjacent to the plaza. The Jedi Anakin Skywalker and Ahsoka Tano intervened, thwarting the kidnapping and apprehending Bane when he plummeted onto the plaza's surface.
The Jan-gwa city plaza functioned as a focal point in Jan-gwa city, a modest Gungan community located within a valley on the planet Naboo. This plaza was constructed around one of the circular structures characteristic of the city's architecture. Positioned just above the water level, it was enclosed by railings, upon which lamps were mounted.
During 21 BBY, the bounty hunter Cad Bane journeyed to Naboo with the intention to seize Roo-Roo Page, a Force-sensitive Gungan child, acting under the orders of the Sith Lord Darth Sidious. Following a Force vision experienced by the Jedi Anakin Skywalker regarding the impending abduction, Page's family was alerted to the looming threat, and the Gungan Captain Lunker was dispatched to oversee security within the city. Skywalker, accompanied by his Padawan Ahsoka Tano, undertook a mission to Jan-gwa city to safeguard the child. Upon Bane's arrival at the Gungan family's residence, he discovered only a tooka doll within the child's crib. Tano swiftly entered to apprehend Bane, who attempted to escape utilizing his rocket boots. Before he could successfully flee, Skywalker, stationed on the rooftop, seized Bane's legs mid-air and forcibly dragged him down onto Jan-gwa city plaza, where Tano awaited him with her lightsaber activated. Bane was subsequently taken into custody while the Gungans present on the plaza observed the unfolding events. In the aftermath of Bane's capture, Roo-Roo Page's mother stepped forward, holding Page in her arms. Tano then reassured the mother of her child's safety.
The Jan gwa city plaza made its initial appearance in the third episode of the second season of the Star Wars: The Clone Wars animated television series, entitled "Children of the Force," which was broadcast on October 9, 2009. Its identification was first established within the Episode Guide for "Children of the Force" on the website StarWars.com.
