In the suburbs of Atlanta, there is a neighborhood that is comprised almost entirely of Victorian and Queen Anne style houses, most of which are painted very bright colors. These are houses that were built in the 1980s, so they are an exaggerated vision of typical Victorian style characteristics: gingerbread styling, intricate filigreed trimwork, towers, wings, wrap-around porches, steeply pitched roofs with gables. Fishscale shingles adorn many of these homes. Years ago, I went to a Christmas party in this neighborhood, and most of the homes were decked out like miniature gingerbread houses, with yards full of decorations and lights everywhere. Unfortunately, I do not have a picture of this neighborhood, and the holiday traffic in Atlanta makes a journey out there a bit impractical!

The fishscale pattern is very characteristic of homes in the Victorian era, in shingles and/or the siding on the homes. It is interesting that many gingerbread houses are often Victorian in nature, and in fact many Victorian houses are often called 'gingerbread houses'. I may need to research the link between the two when I have more time, but for now it seems reasonable to assume that the extensive details and fairytale nature of the Victorian architecture style makes it a good subject matter for a detailed gingerbread house.
