The CWCL is significant because of its idyllic setting, rich history associated with living heritage and distinctive cultural and natural environment; and unique planned landscapes boasting an architectural and aesthetic form unique to South Africa. Of great importance is, it is a site of significance in relating to the history of slavery in South Africa. Ida's Valley is a typical and, at the same time, a special example of this cultural landscape type. It is particularly unspoilt in the context of the Cape Winelands generally.
