RCW~38 is a uniquely young ($<$1 Myr), embedded ($A_V \sim 10$) stellarcluster surrounding a pair of early O stars ($\sim$O5.5) and is one of the fewregions within 2 kpc other than Orion to contain over 1000 members. X-ray anddeep near-infrared observations reveal a dense cluster with over 200 X-raysources and 400 infrared sources embedded in a diffuse hot plasma within a 1 pcdiameter. The central O star has evacuated its immediate surroundings of dust,creating a wind bubble $\sim$0.1 pc in radius that is confined by thesurrounding molecular cloud, as traced by millimeter continuum and molecularline emission. The interface between the bubble and cloud is a region of warmdust and ionized gas, which shows evidence for ongoing star formation. Extendedwarm dust is found throughout a 2--3 pc region and coincides with extendedX-ray plasma. This is evidence that the influence of the massive stars reachesbeyond the confines of the O star bubble. RCW~38 appears similar in structureto RCW~49 and M~20 but is at an earlier evolutionary phase. RCW~38 appears tobe a blister compact H{\small II} region lying just inside the edge of a giantmolecular cloud.
