The Mitchell Building is a five-story bank and insurance building in the Second Empire style. It was built in 1876 and was added to the National Register of Historic Places in 1973.
Alexander Mitchell was a Scottish immigrant who came to the United States in 1839. He led an insurance company, a railroad and a bank, and he served two terms in the U.S. House. He hired architect E. Townsend Mix to design the building. Its first-floor walls are gray Minnesota granite and the upper walls are limestone, with a mansard roof and an ornate central tower.
It is believed to stand on the site of the home of Solomon Juneau, who founded Milwaukee in the 1830s. Mitchell's bank stayed there until 1930. The exterior remains highly intact, though much of the fancy interior has disappeared with remodeling.
