indicating the presence of neutral material at the shock front. The PWN component is highly polarized with a luminosity of L($10^{7} − 10^{11}$ Hz) ∼ $5 × 10^{34}$ erg s$^{−1}$ [@Dickel:2000]. The associated pulsar has not been detected but *Chandra* maps have revealed a point source embedded in the X-ray PWN located in the southwest of the radio nebula [@Temim:2013]. SNR G326.3$-$1.8 was also detected in X-rays by *ROSAT* [@Kassim:1993] and *ASCA* [@Plucinsky:1998] showing a complete shell that spatially correlates with the radio SNR while the width of the PWN in X-rays shrinks near the compact object. At higher energies, previous $\gamma$-ray studies have revealed emission with uncertain origin [@Temim:2013] and SNR G326.3$-$1.8 has only recently been found to be extended with the $\textit{Fermi}$-LAT data [@First_SNRcat:2016].

The latest Large Area Telescope data release Pass 8 [@Pass8:Atwood:2013] allows not only a claim of significant extension of the $\gamma$-ray emission, but also a study of the PWN and SNR contributions separately. This distinction might be crucial for understanding the underlying emission mechanisms and potentially distinguishing between hadronic and leptonic nature of the constituents. In this paper, we briefly describe the latest data release Pass 8 before presenting a morphological study of SNR
