The now beautiful Georgian Houses that make up Rainbow Row didn’t always look so good. In the 1920’s, Susan Pringle Frost, the founder of the Society for the Preservation of Old Dwellings (now the Preservation Society of Charleston) bought six of the buildings which were then in near slum-like conditions. With that, she began one of the first preservation efforts in the United States, even though she did not do the restoration of those properties herself (that was begun by Dorothy Haskell Porcher Legge in 1931).
