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.

The Carnegie-Stout Public Library (1902) is located on the south side of the district.

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.
