We present Chandra imaging and spectroscopy of G327.1-1.1, a composite supernova remnant with a an unusual morphology consisting of a symmetric radio shell and an off center nonthermal component that indicates the presence of a pulsar wind nebula (PWN). Radio observations show a narrow ridge of emission extending from the PWN structure towards the northwest, possibly interpreted as a trail of emission left behind by the moving pulsar. X-ray studies with ASCA, ROSAT, and BeppoSAX revealed elongated extended emission and a compact source at the tip of the ridge that may be coincident with the actual pulsar. The high resolution Chandra observations provide new insight into the structure of the inner region of the remnant. In addition to the compact source and the trail of emission, the Chandra images reveal faint filamentary features originating from the location of the pulsar and extending to the north, beyond the boundary of the radio PWN. The peculiar morphology of the remnant may be explained by the emission from a moving pulsar and a relic PWN that has been disrupted by the reverse shock.
