Rainbow Row is the name for a series of thirteen colorful historic houses in Charleston, South Carolina. It represents the longest cluster of Georgian row houses in the United States. The houses are located north of Tradd St. and south of Elliott St. on East Bay Street, that is, 79 to 107 East Bay Street. The name Rainbow Row was coined after the pastel colors they were painted as they were restored in the 1930s and 1940s.
