Bisbee Residential Historic District - Credit: Wikimedia Commons
The Bisbee Residential Historic District is distinct from the Bisbee Historic District, and is located north and west of that district. It developed in the late 1880s and early 1900s, to support the booming mining industry. While it has some multi-family dwellings, commercial buildings, and a school, it is primarily composed of single family houses. It also has an extensive system of pedestrian walkways and stairways. Bisbee does not follow a grid pattern, rather its streets wind following the contour of the canyon and gulches. Developed prior to automobiles, it has narrow roads which are steep, and still remains a pedestrian-oriented town. It consists of over 500 contributing buildings and structures.
