Charles T. Hancock House

The Carnegie-Stout Public Library is located in Dubuque, Iowa, United States. The public library had its beginnings with the Young Men's Literary Association, established in 1859, and their book collection was the basis for the library's collection. The books were housed in a variety of buildings over the years. The community applied for a grant from Andrew Carnegie who on January 12, 1901, contributed $71,500 to build the library building. Local businessman Frank D. Stout donated the property, which was worth $20,000, in honor of his father Henry L. Stout. The two-story Bedford stone and brick building was designed by Chicago architects W. G. Williamson and John Spencer. It is considered one of the finest examples of the Classical tradition of Beaux-Arts architecture in Iowa. The main facade is dominated by a Roman Corinthian portico that was modeled after the Pantheon in Rome. Its fluted columns are matched with pilasters on the wall behind. The building was dedicated on October 17, 1902, and it opened three days later. It was individually listed on the National Register of Historic Places in 1975, and it was included as a contributing property in the Jackson Park Historic District in 1986. An addition was added to the east side of the building in 1981.

This district is a residential area on top of the bluff above the Jackson Park Historic District, which is in the river valley below. Its name comes from its historical association with the former West Eleventh Street Elevator, a funicular that was similar to the Fenelon Place Elevator to the south. For the most part the historic buildings here are single-family residences with their attendant out-buildings, although the number of out-buildings located here is relatively low. There is one apartment building and 46 duplexes. Some of the single-family houses were converted into multi-family residences, and then some of those were converted back. The various Victorian styles are found along the bluff fronts on the eastern and southern edge of the district, and vernacular structures on the northern and western sections. The Charles T. Hancock House (1890) was individually listed on the National Register. Given the steep bluffs in the district the historic structures are retaining walls and steps that replace the sidewalks.

Jackson Park 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 1986. This is primarily a residential area, with some institutional and commercial buildings, located north of the central business district. The city originally developed just to the south of here. The Cathedral Historic District represents the oldest residential neighborhood in Dubuque, and began to house the working-class people closer to the docks. Once the Jackson Park area opened for development the city's wealthier residents built their homes here. Architectural styles rang from the vernacular, which are found mainly along the bluff, to the high style found mainly along Main and Locust Streets. Most of the houses were built from the mid to the late 19th century. The Andrew-Ryan House (1873) was individually listed on the National Register. Most of the institutional architecture are churches, which include St. John's Episcopal Church (1878) and St. Patrick's Catholic Church (1878).

The Interstate Power Company Building, also known as the Masonic Hall and the Dubuque Electric Company, is a historic building located in Dubuque, Iowa, United States. While a single facility, this is actually two buildings: an 1894 three-story Queen Anne, and a 1956 three-story (later four-story) Modern Movement free-standing addition. The Dubuque Electric Company moved into the older building in 1924, and the following year it was reorganized as Interstate Power Company. This became the headquarters of a regional electrical utility that, at one time, served parts of eight states and a Canadian province. The Great Depression and antitrust court rulings altered the company's fortunes. The 1956 addition was designed to hold the companies large computers in an air-conditioned environment, in addition to office space. Other additions to the building were made in 1962, 1981 and 1989. The facility remained Interstate's corporate headquarters until Alliant Energy bought and absorbed the company in 1996. Alliant continued to use the building for a period of time afterward. It was included as a contributing property in the Upper Main Street Historic District in 2005, and it was individually listed on the National Register of Historic Places in 2008.
