The C.H. Whitehead House is a historic residence located in Marshalltown, Iowa, United States. Whitehead was a Boone County, Iowa native who came to Marshalltown in 1898, where he established a women's and children's clothing store that is thought to be the first of its kind in Iowa. He had this home built around the turn of the 20th century. The house does not exemplify any one style, but is a compilation of several styles. The Queen Anne style is found in overall asymmetry of the main facade, especially the projecting bay and the porch's pediment, as both are off-centered. The Georgian Revival style is found in the rectangular form of the structure, the horizontal proportions, and the Adamesque details. The 17th century colonial architecture of New England is found in the way the second floor overhangs the first floor on the side elevations. The house was listed on the National Register of Historic Places in 1979.

The Marshalltown Downtown Historic District is a historic district located in Marshalltown, Iowa, United States. It was listed on the National Register of Historic Places in 2002. At the time of its nomination it contained 96 resources, which included 79 contributing buildings, one contributing site, and 16 non-contributing buildings. The historic district covers most of the city's central business district. All of it is within the original town of Marshalltown, which was laid out and recorded on August 15, 1853, as the village of Marshall. Confusion with a town with the same name in Henry County led this village to be renamed Marshalltown in 1862. It was incorporated the following year. The district contains a mix of commercial buildings, an opera house, a movie theater, a fraternal hall, and warehouses. The civic buildings include the Marshall County Courthouse, sheriff's residence, municipal building, civic auditorium and public library. The buildings range in size from narrow, two-story commercial blocks to three-story corner blocks, and the seven-story Hotel Tallcorn. The period of significance is from 1862 to 1950, and the buildings are constructed during that time frame. The commercial Italianate, Romanesque Revival, and especially vernacular architecture are dominant. Prominent architects who have buildings in the district include John C. Cochrane (courthouse; 1886), Patton and Miller (public library; 1902), Harry E. Reimer (Marshalltown Municipal Building; 1921), and Josselyn and Todd (Marshalltown Memorial Coliseum; 1929). A tornado struck Marshalltown on July 19, 2018. It did significant damage to many buildings in the historic district, including the courthouse, city hall, and the civic auditorium.

The Newton Downtown Historic District is a nationally recognized historic district located in Newton, Iowa, United States. It was listed on the National Register of Historic Places in 2014. At the time of its nomination it contained 85 resources, which included 60 contributing buildings, one contributing site, and 24 non-contributing buildings. Jasper County was established by the Iowa Territorial Legislature in 1846, and Newton was incorporated the following year as the county seat. The town grew slowly at first around the Jasper County Courthouse. Businesses largely served the needs of the local farmers as well as the town's residents. The Mississippi and Missouri Railroad, later the Chicago, Rock Island and Pacific Railroad, came to Newton in 1867. This changed the town's economy from agricultural-based to manufacturing, and the central business district expanded outward as the community grew. Several washing machine companies established themselves in Newton, most notably Maytag. The emergence of Maytag as a major corporation in the mid-20th century led to the transformation of the downtown area. Between 1951 and 1952, 18 businesses installed new storefronts, transforming them from their original Victorian appearance to a more modern appearance. The modernization continued into the 1960s. Various architects, mostly from Iowa, designed most of the important buildings in the district. The exception was Henry Raeder, a Chicago architect who designed the Hotel Maytag (1926). Most of the buildings in the district, however, were designed by local builder-contractors. All of the buildings are of masonry construction. A majority of the structures housed retail concerns on the main floor with apartments or offices on the upper floors. Other buildings housed banks, restaurants, service stations, the local newspaper, a hotel, and fraternal organizations. Three churches, the Salvation Army, First United Methodist, and First Presbyterian, are located in the district. Government buildings located here include the former city hall, former post office, and county public services. The present county courthouse (1911) is individually listed on the National Register. The courthouse square is the contributing site.

The hotel's sale in 1956 from the Eppley chain to the Sheraton Corporation was part of the second largest hotel sale in United States history. The Tallcorn was listed as a contributing property in the Marshalltown Downtown Historic District on the National Register of Historic Places in 2002.
