Chaleydonia double-towered business center

The North and south towers on Christophosis were two parallel towers in Crystal City. They overlooked the main plaza of the city, and was an ideal place for the Grand Army of the Republic to ambush the battle droid army going through the plaza during the Battle of Christophosis. Anakin Skywalker and Captain Rex were stationed in the North while Obi-Wan Kenobi and Commander Cody were stationed in the south tower. Kenobi's men reported that the droid army unexpectedly split into two, therefor evading the ambush.

Suddenly, battle droids swarmed the South tower and the clone's positions were compromised. Skywalker and his men made their way into the South tower by using ascension hooks in the gap between the two buildings, and the survivors proceeded to the extraction point on the roof of the building.
