RCW121 is a visible HII region at a distance of 2.0 kpc, associated with the IR source IRAS17149-3916. The presence of a 6.7 GHz methanol maser, a water maser and an HII region detected at 18 GHz suggests that RCW 121 is a high-mass star forming region. In order to determine the physical conditions of the complex, we combine new near-IR narrow and broad-band images, near-IR spectroscopy, Herschel PACS and SPIRE images and Spitzer/IRAC images from 3.6 to 8.0μm.
