Geonosian droid factories

The Geonosis droid foundries were a massive subterranean battle droid factory on Geonosis. Located near the Petranaki arena, the foundries were completely automated and hazardous to anyone entering them. Anakin Skywalker, Padmé Amidala, R2-D2 and C-3PO stumbled into the factory when trying to rescue Obi-Wan Kenobi: Anakin lost his first lightsaber, while C-3PO was decapitated.

Safety wasn't a primary concern in the factory, and many Geonosian drones were maimed or killed by mold-stampers. Archduke Poggle the Lesser built a larger factory during the Clone Wars.
