The County seat eventually moved to Dodgeville because of its central location in the 'new' Iowa County. Dodgeville's population grew rapidly, and it became a center for mining and later, dairy product manufacturing and shipping. Miners from England flooded the city, and British and Cornish architecture is still visible in the city today. Dodgeville became the largest city in Wisconsin at the time as well as most of the Midwest north or St. Louis, and west of Cincinnati. The community's boom didn't last long though, and with the decline of mining its population was overtaken by rapidly growing cities like Chicago and Milwaukee.
