Temple Atun was the steepest of the ancient temples of the Massassi on Yavin 4. It was left as it was for thousands of year, except for its outer chambers which had been looted. A trap consisting of two large sliding stones prevented the inner chambers from being entered and still contained the crushed remains of thieves who tried to access it.

Stonebats and kitehawks later made it their home.

Luke Skywalker made it his sanctuary for a period of time and requested that Streen meet him at the top of the temple.
