Cathedral Historic District (Sioux Falls, South Dakota)

Cathedral Historic District, originally the Sioux Falls Historic District, is located in Sioux Falls, South Dakota. Named for its centerpiece and key contributing property, the Cathedral of Saint Joseph, the district covers the neighbourhood historically known as Nob Hill, where multiple prominent pioneers, politicians, and businessmen settled in the late 19th and early 20th centuries. These homes primarily reflect Queen Anne and Mediterranean Revival architectural styles. In 1974, the neighborhood was listed as a historic district on the National Register of Historic Places (NRHP); at the time of this listing, there were 223 buildings, not all contributing, within the district's boundaries. The district was enlarged in 2023.

Location and architecture
The Cathedral Historic District covers 14 blocks and the eastern half of 6 blocks just west of downtown Sioux Falls. It is roughly bounded to the south by West 10th Street, to the east by Spring Avenue, to the north by 4th Street, and to the west by Prairie Avenue. The district is built on an incline and slopes eastwards, towards downtown.

Various architectural styles popular during the late 19th and early 20th centuries are represented by the district's houses. The most common style is Queen Anne architecture, which about 38% of the contributing houses embody. Of the Queen Anne homes, about 15% are of the subclass Queen Anne Cottage. As the popularity of Queen Anne waned after the turn of the 20th century, these houses are among the oldest in the district. Another 23% of houses were built in the slightly newer Mediterranean Revival style. The architectural survey done in preparation for the NRHP listing identified 14 other architectural styles, including Colonial Revival and Richardsonian Romanesque.

The oldest home here was built in 1872; 104 homes—almost half of the contributing structures—were built between then and 1900. An additional 51 homes went up between 1901 and 1910, and another 35 between 1910 and 1920. Although new construction continues within the district, these are comparably rare and few in number. West 10th Street is a commercial corridor, and many of the intrusions into the historic district are located there.

Key contributing properties
Several buildings have been identified as key and primary contributing properties to the district's historical and architectural integrity.
