The Farm House, also known as the Knapp–Wilson House, is the oldest building on the campus of Iowa State University in Ames, Iowa. Now a museum open to the general public, this house was built 1861-65 as part of the model farm that eventually became Iowa State. It was designated a National Historic Landmark in 1964 for its association with agriculturist and teacher Seaman A. Knapp and with U.S. Secretary of Agriculture James Wilson, both of whom lived here while teaching at Iowa State.
The Langworthy House, also known as the Octagon House, is an historic building located in Dubuque, Iowa, United States. Built in 1856, it was designed by local architect John F. Rague for local politician Edward Langworthy. The two-story brick home features tall windows, a columned entry, and a windowed cupola. Langworthy and three of his brothers were among the first settlers in Dubuque. They were partners in a lead mine, helped to build the territorial road between Dubuque and Iowa City, they farmed, invested in real estate, and they owned a steamboat and a mercantile exchange. The house has been passed down through Langworthy's descendants. It was individually listed on the National Register of Historic Places in 1975, and it was included as a contributing property in the Langworthy Historic District in 2004.
The Carl and Ulrika Dalander Cassel House is a historic residence located in Madrid, Iowa, United States. This Greek Revival structure is believed to be the oldest frame house in town. Built in 1862, it is associated with Swedish settlement in Iowa. Carl Cassel came with his father and the first group of immigrants to the Iowa Territory in 1845. They settled in a place they called New Sweden. Anna Dalander led another group of immigrants the following year and intended to settle in the same place, but they took the wrong river and ended up in Boone County. They named their settlement Swede Point, which was later renamed Madrid. Cassel married Dalander's daughter Ulrika in 1848. He and his brothers-in-law operated a grist mill. He also farmed and was involved in local politics. This house was located on the edge of his farm and the town. Cassel probably lived here until his death in 1902. The house was listed on the National Register of Historic Places in 1994.
Daniel Nelson House and Barn, also known as the Nelson Pioneer Farm and Museum, are historic buildings located north of Oskaloosa, Iowa, United States. Daniel and Margaret Nelson settled here in 1844, a year after this part of Iowa was opened to settlement by the U.S. Government. Their first home was a log structure, non-extant, located northeast of the present house. The present house is a two-story, brick structure with a gable roof. The wooden porches on the front and back of the house date from 1898 to 1900. The large barn measures 61 by 46 feet, and was built in 1856. It is composed of board and batten construction from oak that was milled on the site. It was used largely as a granary, rather than a shelter for farm animals. Three other buildings included in the historic designation include the summer kitchen, woodshed, and a small outdoor privy. The dates of construction for the three frame buildings is unknown. The farm remained in the Nelson family until 1941 when it was abandoned with most of the original furnishings intact. The property was donated to the Mahaska County Historical Society, which now operates it as a museum. Other historic buildings have been moved to this location over the years. It was listed on the National Register of Historic Places in 1974.
Paradise Farm are historic agricultural and domestic buildings located west of Bellevue, Iowa, United States. Massachusetts native Elbridge Gerry Potter settled near Big Mill Creek in 1842 from Illinois. He arrived here with 500 head of cattle, 40 teams of mules, and money. In addition to this farm he operated a flour mill and sawmill in Bellevue, and established steamboat lines on the Mississippi River at Bellevue, on the Yazoo River in Louisiana and the Red River in Texas.
The Thomas F. and Nancy Tuttle House, also known as the Tuttle Cabin, is a historic residence located in Pella, Iowa, United States. Built in 1843, it predates the founding of the Pella, and is therefore the oldest building in town. The 1½-story log cabin contains a single room, and was built as a farmhouse for a homestead claim by Thomas Tuttle. In 1847 Pella's founder, Dominie Henry P. Scholte, bought the dwelling and farm from Tuttle for the location of the settlement for Dutch immigrants. Scholte sold the cabin in 1866. The last family to live here was the Sneller family who lived here from 1912 to 1973. Robert Van Vark bought the cabin at an auction in 1973 and his daughter, Gail Van Vark Kirby, inherited it from him. The house was listed on the National Register of Historic Places in 2015. The Historic Pella Trust acquired the property in April of the same year.
The Andrew P. Hansen Farmstead is a collection of historic domestic and agricultural buildings located northwest of Brayton, Iowa, United States. Hansen was born in Fyn, Denmark, and was five years old when the family immigrated to the United States, settling in Avoca, Iowa. He worked for the Chicago, Rock Island and Pacific Railroad there before buying his first 40 acres (16 ha) from the railroad. The farm eventually grew to 120 acres (49 ha). It was listed on the National Register of Historic Places in 1991. At the time of its nomination the farm included five contributing buildings including the transverse-frame dairy barn (1894), the hog house, the 1½-story American Foursquare house (1901), the Midwest three portal cattle barn (1903), and a garage (1910s). It also includes one contributing structure, the double corn crib. The house and the barns are characteristic of the building trends that are associated with Danish immigrants during the period of significance, in this case 1894–1924.
The Parker House is a historic building located in Guttenberg, Iowa, United States. This two-story brick structure with a brick lean-to addition, which houses the kitchen, was built in 1858.

The Carstens Farmstead is a collection of historic buildings located south of Shelby, Iowa, United States. Johan Carstens was a German immigrant who spent eight years living and working in Milwaukee, Chicago, and Davenport, Iowa before settling in Pottawattamie County in 1871, where he established this farm. He bought 160 acres (65 ha) of land from the Chicago, Rock Island and Pacific Railroad, and continued to farm it until he and his wife retired in 1905. The farm remained in the Carstens family until 1977, when the last of the 80 acres (32 ha) was donated to the Pottawattamie County Historical Society. The farm buildings include: the original farmhouse (1872), the 1888 farmhouse with the summer kitchen, an outhouse, garage (1917), granary (1898), horse and dairy barn (1886), beef cattle barn (1903), beef cattle barn (1917), forge and workshop, windmill (1916), feed shed (1919), hog house (1919), poultry house, machine shed (1920), the cob house (1926), and a corn crib (1930).

Mary Elizabeth Day Nursery, also known as Mary Elizabeth Day Care Center, is a historic building located in Sioux City, Iowa, United States. This is the oldest child day care facility in the state of Iowa, and the state's second-oldest preschool. The Sioux City Day Nursery was established in 1914 by the Wall Street Mission, a local settlement house operated by the Methodist Episcopal Church. They moved here in 1926, which is the first building designed as a day nursery in Iowa. The two-story brick Renaissance Revival building was designed by local architect Jurgen A. Raven, and built by The Lytle Company, a Sioux City construction firm. Parents were responsible for paying for at least part of their children's care, but it was also subsidized by religious institutions, private associations, and individuals. During the Great Depression, both the federal and state governments began to fund and license child care. The Works Progress Administration was involved in the 1930s. A garage and playhouse designed by Sioux City architect Knute E. Westerlind was built in 1940, and it is part of the historic designation. The facility was renamed the Mary Elizabeth Day Care Center in 1990. The building was listed on the National Register of Historic Places in 1997.
The John and Marie (Palen) Schrup Farmstead Historic District is a nationally recognized historic district in Dubuque County, Iowa, United States. It was listed on the National Register of Historic Places in 2009. At the time of its nomination it consisted of four resources, which included three contributing buildings and one non-contributing building. The three buildings include a stone house, barn, and well-house. The buildings are typical of those constructed by immigrant families from Luxembourg that settled in Dubuque and nearby Jackson counties. The front part of the house is the oldest structure here and was built when Martin Burkhart owned the property. He sold the farmstead to Casper Burkhart the following year, who then sold it to John and Marie Schrup in 1856. The Schrups were responsible for adding onto the back of the house about the time they bought it and the other two buildings. The dairy farm of 193 acres (78 ha) remained in the family until 1973. Because it was always a modest enterprise, the stone buildings were not torn down and replaced with modern structures as happened on many of the Luxembourgian farms built in the mid-19th century. A wooden shed was built in the early 20th century, and is the non-contributing building. A pole barn was also added to the farmstead and it fell down c. 1995.
Four Mounds Estate 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 2002. At the time of its nomination the district consisted of 19 resources, including 11 contributing buildings, two contributing sites, four non-contributing structures, and two non-contributing buildings. The estate is named for the four conical burial mounds that are located on the property. They are one of the historic sites, and they are individually listed on the National Register of Historic Places.
The Laboratory of Mechanics, formerly known as Engineering Hall, is a historic building on the campus of Iowa State University in Ames, Iowa, United States. The two-story, brick structure with a mansard roof is a simplified version of the Second Empire style. It features a three-story tower with a mansard roof at the main entry. The original building was "L" shaped, designed by J.B. Ballinger, and built by V. Tomlinson. Its first addition was designed by the Des Moines architectural firm of Foster & Liebbe, and completed in 1885 by Tomlinson. Other additions were completed in 1933 and 1997.
The Joseph A. and Lydia A. Edwards House is a historic building located east of Salem, Iowa, United States. This two-story structure is a rare stone building in Henry County, and it reflects building construction from the settlement period of the county. Joseph Edwards acquired this farm in 1841. He initially lived in a house located to the west, and this house replaced it in 1866. The Italianate style residence features a symmetrical facade, flat stone lintels and window sills, a cubical form capped with a hip roof, and a wide frieze with paired brackets. It is believed that the stone for the house's construction was quarried on the north side of the Edwards' farm. The house was listed on the National Register of Historic Places in 2015.
The Owen A. and Emma J. Garretson House is a historic building located east of Salem, Iowa, United States. Its significance is derived from its association with Owen Garretson, a local farmer, politician, and historian. His parents, Joel C. and Elizabeth (Goodson) Garretson, were two of the earliest settlers in Henry County, settling here in 1837. The elder Garretson's were opposed to slavery and their farm house was a stop on the Underground Railroad. Owen farmed with his father, and eventually acquired his father's farm. He was involved locally and on the state level with the People's Party, served as a county supervisor, and on the boards of local institutions. Garretson was the president of the Henry County Historical Society, and was a member of the State Historical Society of Iowa. He wrote several articles on the history of Henry County and southeast Iowa that were published in Palimpsest and the Iowa Journal of History and Politics.
The Sylvanus Johnson House, also known as Pinehurst, is a historic building located in Iowa City, Iowa, United States. Johnson was a Connecticut native who worked in his father's brickyard before moving to Iowa in 1837. He opened the first brickyard in Iowa City and provided the bricks for many of its oldest buildings, including the Old Capitol. He also provided the bricks for his own house, which is the first in the area to have a mansard roof. Because the floor plan is very similar to the 18th century double-hipped roof houses in his native Connecticut it is very possible they were the inspiration for this house. The Second Empire style, which this house also resembles, would not become popular until after the American Civil War. The house was listed on the National Register of Historic Places in 1990.
The Nicking House is a historic building located in Iowa City, Iowa, United States. Henry C. Nicking, who was a barber, had this house built in 1854. It is one of the oldest houses in the city, and one of a very few that was constructed using sandstone. The general architectural style is a stripped-down version of the Greek Revival style, but a rear addition gives it a saltbox appearance. It features a symmetrical facade, side gable roof, limestone lintels and window sills, and cornice returns on the front. The house was listed on the National Register of Historic Places in 1975.
The Longfellow Historic District is a nationally recognized historic district located in Iowa City, Iowa, United States. It was listed on the National Register of Historic Places in 2002. At the time of its nomination, it consisted of 355 resources, which included 250 contributing buildings, 103 non-contributing buildings, and two non-contributing structures. As the University of Iowa expanded in the early 20th-century new sections were being added to the city. The Longfellow neighborhood, named after the local elementary school completed in 1919, was part of this expansion. The northern part of the neighborhood along East Court Street developed in the 19th century because the street connected the city center to the Muscatine road. The rest of the neighborhood was platted on farm land in 1908 and 1914. A trolley line was completed to the area in 1910, leading to the creation of suburban development.
The First Johnson County Asylum is a historic building located on the far west side of Iowa City, Iowa, United States. The first facility Johnson County built to care for paupers and the mentally ill was a four-room cabin in 1855. Two wings were added to the original building six years later. All that remains of this structure is this wing that housed the mentally ill. The single-story wood-frame structure with a gable roof was used by the county for this purpose until 1886 when a new facility was completed. It was initially thought that it was built in 1859, but later research revealed that it was built in 1861 and that it was moved a short distance to this location in 1888. This building served for many years as a hog building on the Johnson County Poor Farm. It is now part of an education-based farm program called Grow:Johnson County. The building was individually listed on the National Register of Historic Places in 1978. In 2014 it was included as a contributing property in the Johnson County Poor Farm and Asylum Historic District.
Seminole Valley Farmstead is a collection of historic farm buildings located in Seminole Valley Park on the west side of Cedar Rapids, Iowa, United States. The historic designation includes the farmhouse, summer kitchen, livestock barn, tool shed, ice house, chicken house, and smokehouse. There is also a small orchard and a garden. The complex is located near a bend in the Cedar River. The farm represents a transitional period between Iowa's austere pioneer farms and the mechanized farms that developed later in the 20th century. The nearby timber was a source of raw materials for the farm, the fertile bottomland on which it is located provided rich soil for grazing and cultivation, and the smokehouse and ice house were used to preserve agricultural products for later consumption. At the same time the barn and the chicken house were more substantial than those from earlier times. It was listed on the National Register of Historic Places in 1976.
