With the opening of the Black Hills region of South Dakota due to the discovery of gold in 1874, the business-savvy founders of Rapid City, in 1876, saw the potential of this area as a focus for urban development. It was nestled within the beauty of the Black Hills, rich in natural resources, adjacent to a viable water source and in line with major trade routes. Thus, a thriving commercial district evolved, the architecture of which reflects the distinctive periods of a community's growth from a frontier "hay camp" town to a regional metropolitan center. The built environment of Rapid City embodies and exemplifies the skill of local craftsman in interpreting the prevailing stylistic trends, the utilization of local materials, and other cultural influences. All of these elements provide Rapid City with an identifiable character and sense of place that is, clearly and uniquely, South Dakota.
