Bishop's Block

Schroeder-Klein Grocery Company Warehouse, also known as the Shields & Bradley Block, is a historic building located in Dubuque, Iowa, United States. It was built to house the warehouse needs of the Schroeder-Kleine Grocer Company and the M.M. Walker Company, two of the most prominent wholesale food distributors in the upper Midwest at the turn of the 20th century. Local builders Shields & Bradley constructed the three-story warehouse in 1894 so that the two firms could operate independent of each other. When the two firms merged in 1921, the building became fully interconnected. It was used as a food distribution warehouse until 1959. Other commercial ventures that have been housed here have included beer and soda bottling and distribution, chemical production, overhead door sales, hair products retailer, and pet groomer. In addition to its commercial importance, the building is also considered a significant example of a late 19th century Romanesque Revival warehouse. This was one of several large warehouses built in that style during the same time period in the city, and it is one of few that is still extant. Elements typical of the style found in this building include its massive limestone base, limestone string courses, brick corbelling, and round-arch windows. The building was listed on the National Register of Historic Places in 2011.

Old Main Street Historic District is a nationally recognized historic district located in Dubuque, Iowa, United States. It was listed on the National Register of Historic Places in 1983. At the time of its nomination it consisted of 33 resources, which included 30 contributing buildings and three non-contributing buildings. In 2015 the boundaries were increased to include five more buildings. Four of the buildings are contributing properties that were excluded from the original district because they were slated to be torn down as a part of the expansion of U.S. Route 61. While the highway was built the buildings were spared. The fifth building is non-contributing as are three structures. This is primarily a commercial area located immediately south of the central business district. Originally, this is where the city's commercial district was located because of its proximity to the ferry and riverboat landings. After 1860 most of the larger retail businesses, banks, and professional offices moved further north on Main Street, and new wholesale businesses moved here and built new structures. The buildings are all constructed in brick and are between three and four stories tall. It is considered to be the "largest concentration of significant nineteenth-century commercial architecture" in Dubuque. The Bishop's Block (1887) and the German Bank (1901) are individually listed on the National Register, and the Hotel Julien Dubuque (1914) is also a contributing building.

Passenger service ceased upon the formation of Amtrak in 1971, but resumed between Chicago and Dubuque in 1974 under the name Black Hawk. Service ceased on September 30, 1981.

German Bank is a historic building located in the Lower Main Street district of Dubuque, Iowa, United States. The city's German community was its most prominent ethnic group in the mid to late 19th century. Like many other Iowa cities of that era, Dubuque had banks that were owned by, and catered to, members of their particular immigrant communities. T.H. Thedinga, the city's first German-born mayor, started this bank in 1864 to serve immigrant Germans. In 1868 it moved from its original location on Main Street and into the former Dubuque Miners' Bank building. That building was torn down in 1901 in order to construct this one. It was designed by Dubuque architect John Spencer in partnership with Chicago architect W.G. Williamson. The three-story brick building has a highly decorative main facade composed of polished pink granite on the main floor and terra cotta on the upper two floors. Decorative elements include egg-and-dart, Greek fret, a row of small lions' heads, bay windows, scroll pediments, imperial German eagles, and a bracketed cornice with dentils. The second and third floors are dominated by four fluted, banded columns with Corinthian capitals. The bank remained in operation here until 1932 when it closed in the Great Depression. Since 1946 the first floor has housed a restaurant and bar. The building was individually listed on the National Register of Historic Places in 1978. and it was included as a contributing property in the Old Main Street Historic District in 1983.

The Dubuque Freight House is a historic building located in Dubuque, Iowa, United States. Built by the Chicago, Burlington and Northern Railroad (CB&N) in 1901, this was the third and last freight house built by a railroad in the Ice Harbor area. The other two facilities were built by the Illinois Central Railroad (1872) and the Chicago, Milwaukee and St. Paul Railroad (1874). These other two railroads were older, larger, and monopolized the bridge and tunnel that crossed the Mississippi River. The CB&N was fortunate that their freight house was located along the water's edge in that the river boats could tie up next to the building and load and unload cargo, and the railroad put box cars on ferries that docked in the Ice Harbor. The Dubuque Boat and Boiler Works were headquartered on the west end of the facility for 20 years beginning in 1952. Founded in 1852 as the Iowa Iron Works, they provided engines, boilers and other equipment for river boats, and water craft for the United States Navy, United States Coast Guard, and the United States Army Corps of Engineers. The building was listed on the National Register of Historic Places in 1979. It is now a part of the National Mississippi River Museum & Aquarium.
