Pau City
this sinkhole city was ostensibly the capital of the planet Utapau, during the final years of the Old Republic. Like all such sinkhole cities, Pau City's upper levels were continually buffeted by the hyperwinds that scoured the surface of Utapau. These levels were set aside for population by large windmills that generated huge amounts of free power. Shortly after the First Battle of Coruscant, when General Grievous fled the Core Worlds and hid on Utapau, he established a base of operations in Pau City. The city then became a battleground when Obi-Wan Kenobi arrived to destroy Grievous, as the battle droids of the Separatists fought against the clone troopers who accompanied Kenobi to Utapau. More than half the city was damaged to destroyed in the fighting.
