One-arcsec resolution imaging of the nuclear region of the starburst galaxy NGC 253 in the near-IR lines of forbidden Fe II 164 micron, Brackett-gamma, and H2 1-0 S(1), together with the adjacent continuum, is presented. An emission region extended some 10 arcsec northeast of the nucleus, with several embedded compact peaks or hot spots, is revealed. The line emission from H2 and Br-gamma are closely matched in the circumnuclear region. The H2 emission reveals wispy structures which are more prominent to the northwest of the nucleus. It is proposed that the Br-gamma and H2 emission lines are excited in star formation regions and that the forbidden Fe II emission traces the distribution of SNRs.
