We present a recent Chandra ACIS-S observation of the Circinus galaxy. Several emission components are seen within 1 arcmin of the nucleus: these include (1) a Compton thick Seyfert 2 nucleus, (2) a plume-like structure extending from the nucleus to the NW, probably associated with the bi-conical structure seen in the optical, (3) extended X-ray emission from hot gas in the ENLR, and (4) several bright compact X-ray sources with luminosities, if they reside at the distance of Circinus, in the range 1037--1039 erg s-1. We will discuss the spectra of these components and attempt to distinguish between photoionized and collisionally ionized gas in the extended components. This reserch made use of funding through NASA grant NAG-81027.
