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). Central High School, no longer extant, was located across from Jackson Park, and it was also individually listed on the National Register before its demise. The Carnegie-Stout Public Library (1902) is located on the south side of the district.

It is also one of a small number of double storefront blocks that remain in the downtown area. The building is named for Henry Ziepprecht a German-born druggist who settled in Dubuque in 1856 and died in 1887. His estate paid to have this building constructed on the location of an older building that housed his drug store. Now managed by Joseph Wittmer, the drug store and a confectionery were the first businesses to occupy the storefronts. The upper floors housed apartments. The building was listed on the National Register of Historic Places in 2002.

The John Bell Block, also known as the German Bank & Trust Building, is a historic building located in Dubuque, Iowa, United States. The three-story brick commercial Italianate building was constructed by local businessman John Bell in 1886. Its location on the north side of the central business district meant that it housed several businesses owned by the city's German immigrant population. Chief among them was the German Trust and Savings Bank. It became a tenant when the building was completed and it remained until it built its own building in 1922. In 1918 anti-German sentiments that resulted from World War I forced the bank to change its name to Union Trust and Savings Bank. It remained in operation until 1932 when a run on its deposits as a result of the Great Depression forced it to fail. Its building was taken over by Dubuque Bank and Trust. Three prominent Dubuque professionals also had offices on the second floor of the building. German-born architect Martin Heer had offices beginning in 1888. He partnered with another German-born architect, Guido Beck, from 1889 to 1895. Beck was noted for his commercial blocks and churches. Contractor Anton Zwack had offices here from 1911 to c. 1965. The building was listed on the National Register of Historic Places in 2002. An early tenant was Baumgartner and Kleih Hardware store

Dubuque architect John F. Rague served as the supervising architect during construction.

It features a gable roof with bracketed eaves. Each gable has a circular window. The 11-foot (3.4 m) tall windows are located in bays defined by arches. The building was first occupied in February 1858. Initially, the main floor was divided into stalls. They were converted into additional office space for the city when the market relocated. The third floor ballroom was converted into an archery and pistol range for the police department, a bowling alley, and a horseshoe pitching area.

The Upper Central Avenue 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 2012.

This six block section of Central Avenue is located on the north side of the central business district. The largely linear district includes a jog at 18th Street. Below the jog the street was originally named Clay Street and above it Couler Avenue. It was also the dividing line where all commerce used the German language exclusively to the north. At one time the street featured a streetcar route and it was a significant farm-to-market route and a gateway into the city from the north. The period of significance for the district covers the years 1856 to 1919, but its historic commercial development occurred during the 1870s and 1880s. The buildings were constructed in brick and are largely two to three stories tall. There are also several single-story buildings and one that is four stories tall. The Italianate and the Queen Anne are dominant. Nine of the buildings are major commercial blocks. In addition to the commercial buildings, there is the two-story, brick, former Fire Engine House Number 1 that faces south at the jog in the street. The buildings in the district are considered some of the best examples of late-19th-century commercial designs in the city.
