Spearhead
From Wookieepedia, the Star Wars wiki.
Spearhead was a Gungan city on Naboo some 3,000 (or 3,032 BBY) years before the Battle of Naboo.
A fortress-city, Spearhead was the headquarters of rogue warlord Boss Rogoe. The fortress was divided between surface and submerged buildings and was said never have fallen in the history of Gungan warfare.
The city's walls fell as it came under siege of Boss Gallo's united Gungan Grand Army and the Bongomeken Collective during the Battle of Spearhead. Rogoe was killed, and Gallo built a new city on the grounds of Spearhead to serve as a capital for the newly united Gungan people: Otoh Gunga.
