The historic Broadway corridor encompasses one of the highest concentrations of historic theaters on a single street, many of which feature groundbreaking engineering achievements and architectural innovations. Cinematic shows, vaudeville entertainment, and commercial retail thrived along the corridor in the early 20th century, and the architectural legacies of this time remain standing today. Advocates for the historic theaters have created foundations and initiatives to restore and revitalize the area. The UCLA Architectural Reconstructions on Broadway Project works with these groups to document the historic records and theater buildings in order to better understand the architectural practices surrounding these landmarks and to support their conservation.
