47th Street was and remains the hub of the Bronzeville neighborhood. In the early 21st century, it has started to regain some of its former glory. Gone for good is the Regal Theater (demolished in 1973), where many great performers took the stage. The Forum Hall building was built in 1897 designed by Chicago archict Samuel Atwater Treat (1839-1910) and may contain the oldest hardwood ballroom dance floor in Chicago. It filled a significant role in Bronzeville's cultural scene, being the venue for famous musicians From the 1940s and 1960s, high-rise public housing projects were constructed in the area, which were managed by the Chicago Housing Authority. The largest complex was the Robert Taylor Homes. They developed severe social problems exacerbated by concentrated poverty among the residents and poor design of the buildings. This project was demolished in the late 1990s and early 21st century. The nickname "Bronzeville" was first used for the area in 1930 by James J. Gentry, a local theater editor for the "Chicago Bee" publication. It refers to the brown skin color of black Americans, who predominated as residents in that area. It has become common usage over decades.
