We report the results of a 60 ks imaging observation of the nearby (D=33 Mpc) giant elliptical galaxy IC1459 with Chandra ACIS-S. IC1459 is notable in that it hosts a massive Black Hole at its nucleus, with a radio-loud compact AGN. This AGN is peculiar in having only weak signatures of activity in the optical/UV, and relatively faint X-ray emission, with a hard component detected with ASCA. With Chandra we can clearly isolate all the X-ray emission components of this galaxy. We detect bright nuclear emission, a population of point-like sources, most likely X-ray binaries, and diffuse emission from a hot ISM. We will discuss these results in the talk, and their implications for the nature of the nuclear source.
