Otoh Gunga / Legends Otoh Gunga , also known as Gunga City , was the largest Gungan city on Naboo , and the seat of their government . Characteristics . The city of Otoh Gunga was anchored to a massive underwater cliff deep within Lake Paonga , and was a mass of hydrostatic bubbles which keep water out while allowing the Gungans to enter through them . There were satellite clusters outside of the city , including buildings which had been cast out from other Gungan settlements . While the Gungans could survive both on land and underwater , they chose to build their capital city under Lake Paonga to avoid contact with the Nabooian Humans . History . Otoh Gunga was founded by Boss Gallo in 3000 BBY on the site of Boss Rogoe ' s fortress city , Spearhead . Otoh Gunga was originally occupied by the population of Otoh Jahai , Otoh Langua , Otoh Mandassa , Otoh Raban , Otoh Sancture , and Otoh Urs , after Gallo united all the Gungan tribes under one banner . As of the Battle of Naboo , Otoh Gunga was home to a million Gungans living in a massive bubble city that had grown out from the original foundation laid by Gallo ' s people , an area now known as the Ancient Quarter . The main focus of the city was a dense cluster of bubbles in the central district , radiating out from between walkways and plazas . Notable additions to the city included the Otoh Villages , where most Gungans lived and worked , and the City Bigspace , a popular concourse constructed on the orders of Boss Rugor Nass , wishing to leave his mark on the city . The city also included bongo pens , cantinas and one of its most famous attractions , the Otoh Gunga Zoological Research Facility . After standing for three thousand years as a symbol of Gungan unity and strength , Otoh Gunga fell to the might of the Trade Federation in the latter stages of the Invasion of Naboo in 32 BBY . In the early stages of the invasion , the Trade Federation had only heard rumors of a primitive underwater civilization . Having confirmed the existence of the Gungans , Nute Gunray ordered a full assault on their strongest fortress . Led by OOM - 9 and assisted by Darth Maul , a contingent of battle droids and aquatic destroyers attacked and besieged Otoh Gunga . Demoralized and defeated , Boss Nass informed the Rep Council of the situation , trying to convince the Rep s they needed to evacuate soon before the city was destroyed . Many members of the council wanted to stay , but Rep Been finally convinced them to go . He knew the secrets of old Gungan hidden places , and suggested they fled to the Gungan ' s Sacred Place to plan his counterattack . After Boss Nass joined with the Royal Naboo Security Forces to expel the Trade Federation of Naboo , Otoh Gunga was re - occupied . Many years later during the time of the Clone Wars , Lyonie had become the Boss of Otoh Gunga . He fell under the sway of Minister Rish Loo , who had allied with the Confederacy of Independent Systems and forced Lyonie to call the Gungan Grand Army together to march against the Royal Naboo . Senator Padmé Amidala and the Jedi Knight Anakin Skywalker traveled to Otoh Gunga and revealed Loo ' s treachery in time for the Grand Army to expel a Confederacy invasion force . Several years later , during the early stages of the Galactic Civil War , Otoh Gunga was advertized as a visitable locale for the Star Tours travel agency . In addition , a Star Tours vessel briefly passed by this area when attempting to access a Rebel - owned hangar on Naboo during a skirmish in the orbit of Naboo . Behind the scenes .
