The Gungan Caves were a system of artificial caves on Naboo, probably built by the Elders. The caves contained ancient golden statues. Around 32 BBY, an young, new recruit of the Jedi Order was sent on Naboo to recover the statues.
The Gungan Caves were a maze of underground tunnels, partially under water. At the center of the caves system, a circular area featured four sealed doors leading to the sacred statues. Each door was to be opened with the help of ten jewelled keys that had been scattered throughout the caves. Carving on the doors depicted animals from the wildlife of Naboo, namely a shaak, a kaadu, a opee sea killer and a peko-peko.
