We present Chandra observations of the galaxy cluster A4059. We find strong evidence that the FR I radio galaxy PKS 2354-35 at the center of A4059 is inflating cavities with radii similar to20 kpc in the intracluster medium (ICM), similar to the situation seen in Perseus A and Hydra A. We also find evidence for interaction between the ICM and PKS 2354-35 on small scales in the very center of the cluster. Arguments are presented suggesting that this radio galaxy has faded significantly in radio power (possibly from an FR II state) over the past 10(8) yr.
