The author reviews the large scale structure of the Orion Nebula, incorporating recent results from 21 cm absorption studies, optical emission line investigations, and Hubble Space Telescope imaging. The ionization structure at the brightest ionization front is clearly defined and demonstrates a well organized flow away from the front. The ionized portion is moving rapidly into the Orion Molecular Cloud and the new images reveal recently formed low mass stars surrounded by protoplanetary disks.
