We present results from 24 ksec XMM-Newton observations of the central part of SNR G156.2+5.7. The X-ray morphology shows an elongation towards the southern regions. A three-color image which was derived from 0.4-1.0 keV, 1.0-2.0 keV and 2.0-5.0 keV energy bands shows increased abundances of 0 and Ni, suggesting that G156.2+5.7 is an O-rich SNR. The relative abundances obtained from models suggest that this remnant has originated from a core-collapse supernova explosion.
