From 1997 to 2003 the UCLA Cultural Virtual Reality Laboratory (CVR Lab) created a digital model of the Roman Forum as it appeared in late antiquity. The notional date of the model is June 21, 400 A.D. From 2002 to 2005, with generous support from the National Science Foundation, the CVRLab was able to create this Web site about the digital Forum model. The purposes of this site are to use the Internet to permit free use and easy viewing of the digital model by people all over the world; to provide documentation for the archaeological evidence and theories utilized to create the model; and to offer basic information about the individual features comprising the digital model so that their history and cultural context can be readily understood.
