The Junk Temple was a crude makeshift replica of the Jedi Temple on Coruscant, erected on the planet Raxus Prime. It was constructed by the insane Jedi Master Kazdan Paratus, who was on the run from the Galactic Empire.
The Junk Temple stands out amidst the waste-covered surface
Among the detritus present on Raxus Prime stood a twisted mirror of the Jedi Temple on Coruscant. This bizarre copy fed Kazdan Paratus's delusion that the Jedi Order had never fallen. A number of junk mannequins of each former Jedi Council member were present within the temple and posed as if they were alive and in a meeting.
After surviving Order 66, Paratus fled from civilization to the junkyard planet Raxus Prime. Unfortunately, the loss of everything he had ever known in life coupled with his seclusion on Raxus Prime, drove him insane. In a desperate attempt to cling to the Jedi Order, Paratus constructed a crude yet accurate replica of the Jedi Temple on Coruscant out of waste refuse on the planet's surface. This Temple was guarded by Junk golems that Paratus also built himself, and included the four spires of the Jedi, complete with a Jedi Council chamber and robotic Jedi Masters. These all were destroyed by Darth Vader's secret apprentice, Starkiller. Paratus was also fatally injured by Starkiller, allowing the crazed Jedi to become one with the Force.
