Fourth Street Historic District (Sioux City, Iowa)

The Evans Block, also known as Northwestern National Bank Building, is a historic building located in Sioux City, Iowa, United States. The city experienced a building boom that began in the late 1880s and continued into the early 1890s. Fred T. Evans, an entrepreneur who had business interests in Iowa, Nebraska and South Dakota, had this building constructed to house Northwestern National Bank of which he was the president. The bank occupied the main level and other offices were housed on the upper floors. Local architect Charles P. Brown designed the four-story Romanesque Revival style building. The Black Hills sandstone for the public facades was from Evans' quarry. The Panic of 1893 brought Sioux City's building boom to an end, and the Evans block was sold in January 1895. Subsequently, the building has housed a hotel, a factory, a saloon, and a variety of stores. It was individually listed on the National Register of Historic Places in 1985, and as a contributing property in the Fourth Street Historic District in 1995.

The Boston Block, also known as Aalfs Manufacturing Company, is a historic building located in Sioux City, Iowa, United States. The city experienced a building boom that began in the late 1880s and continued into the early 1890s. One of the major players in that building boom was the Boston Investment Company, a company on the East Coast who built four large commercial blocks in Sioux City simultaneously. Construction on the four buildings began in 1890 and they were completed the following year. In addition to the commercial blocks, they also built a steam heating plant that provided steam and light to three of the buildings as well as to neighboring buildings. The Massachusetts Block (no longer extant) on the southwest corner of Fourth and Jackson was six stories tall and had a similar facade as the Boston Block, which is five stories tall on the northeast corner of Fourth and Virginia. The Plymouth Block on the southeast corner of Fourth and Locust was also five stories tall, and the Bay State Block on Fourth Street is the shortest at four stories. Among the building's tenants was the Aalfs Manufacturing Company, which used the building as its headquarters. The architect of the four buildings is unknown, but John G. Mainland served as supervising architect. The Boston Block is a Richardsonian Romanesque structure that features rusticated stone veneer with a two-story iron and glass storefront. The original storefront was extensively altered in 1948, and it was altered again in 1984. The building was individually listed on the National Register of Historic Places in 1985, and as a contributing property in the Fourth Street Historic District in 1995.

The Sioux City Linseed Oil Works is a historic building located in Sioux City, Iowa, United States. It is located east of the central business district where warehouses and other industrial buildings are located. It housed the Sioux City Linseed Oil Works (initially known as Hubbard and Gere) from 1884, when it was built, until 1927 when its owner, the American Linseed Oil Company, ceased production here. The building was largely destroyed in a fire that began late in the night of May 20, 1891. Mankato, Minnesota architect William D. McLaughlin stepped in to complete the work begun by Sioux City architect E.W. Loft. The building was rebuilt and was very similar in appearance to the original structure. The gable roof on the westernmost wing was replaced by a flat roof, and two floors were added to the rebuilt press room annex in the back. The building was acquired by Bekins Van and Storage Company in 1928. They began operations here two years later and remained the primary tenant in the building until 1972. There was a variety of other tenants who were housed here over the years. The building was listed on the National Register of Historic Places in 2008.

The Sioux City Fire Station Number 3, also known as the Firehouse Bar, is a historic building located in Sioux City, Iowa, United States. The city's fire department began when a group of volunteers formed the Fire Protection Organization in 1869. It was formally organized in 1876. This building was completed in 1929, and replaced an older structure from around 1884. Station Number 3 served an area that mostly contained commercial buildings on the east side of downtown and a warehouse district along the Floyd River. It served as the fire department headquarters for a short time when Station Number 1 was abandoned. It long served as a training station, and a wooden training tower was located here from at least 1924 and into the 1960s. The building itself followed the "storefront" model for a fire station where the apparatus was housed on the main floor and living quaraters above. It features basket weave brick panels and concrete ornamentation for the pilaster bases and capstones, banding, and parapet. The building is similar to Station Number 7 that was built in the Leeds neighborhood in 1937. That suggests the same architect, who is unknown, but local lore suggests William L. Steele may be the architect. A design for Fire Station Number 1 from 1922 is attributed to him, although never built, and is similar to the two stations that were built. The building was listed on the National Register of Historic Places in 2008, and now houses a bar.

Sioux City () is a city in Woodbury and Plymouth counties in the northwestern part of the U.S. state of Iowa. The population was 85,797 in the 2020 census, making it the fourth-most populous city in Iowa. The bulk of the city is in Woodbury County, of which it is the county seat, though a small northern portion is in Plymouth County. Sioux City is located at the navigational head of the Missouri River. The city is home to several cultural points of interest including the Sioux City Public Museum, Sioux City Art Center and Sergeant Floyd Monument, which is a National Historic Landmark. The city is also home to Chris Larsen Park, commonly referred to as "the Riverfront", which includes the Anderson Dance Pavilion, Sergeant Floyd Riverboat Museum and Lewis and Clark Interpretive Center.

Albertson and Company-Rocklin Manufacturing Company is a historic building located in Sioux City, Iowa, United States. Completed in 1912, the building initially housed Automatic Valve Seating Mach Co. They reorganized in 1914 and became the Sioux City Machine and Tool Company, which produced spark plugs and tire valves. The company failed four months later and the shop foreman, Frans Oscar Albertson, formed Albertson & Co. and took over the plant. During World War I they supplied 6,000 piston rings and repair tools for munition plants for Canada. Albertson never owned the building and moved his operations to another Sioux City building in 1920. The company went on to become the largest manufacturer of portable electronic and air tools in the world. They changed their name to Sioux Tools Inc., and in 1993 they became a division of Snap-On Tools. Their manufacturing facility moved to North Carolina in 2001. Between 1921 and 1942, this building had several owners and uses. I.J. Rocklin acquired it for his company in 1942. He founded his farm equipment business in 1934 and expanded during World War II manufacturing equipment for the Chrysler Corporation, International Harvester, and Allis Chalmers. They also supplied the Chicago Ordnance District and the Tank Automotive Center at the Detroit Arsenal. Their expansion at that time included building two additional structures on the same property. After the war, they no longer need all of the space and consolidated their operations into the newer buildings while letting the 1912 structure deteriorate. Rocklin developed the Rocklinizer in the 1960s. It "applies a thin coating of tungsten or titanium carbide to industrial surfaces (like the tip of a drill bit), lending an extremely durable edge. Decades later the firm developed the MoldMender, which repairs steel molds and dies." When the company decided to move from its World War II-era buildings they chose to renovate their historic building rather than tear it down and build a new structure. Renovations began in early 2017 and were completed in August 2018. The two-story brick building was listed on the National Register of Historic Places in 2019.

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 Sioux City Free Public Library is a historic building located in Sioux City, Iowa, United States. The library was located in a section of the Municipal Building, no longer extant, between 1892 and 1913. It had outgrown the space when the Library Board contacted Andrew Carnegie in 1910 about providing the funding for a new library building. Their request was initially turned down. They chose to work with New York City architect Edward L. Tilton, an architect preferred by Carnegie, in place of local architect William L. Steele who was working with the board previously. Local resident George Murphy donated the property for the new building. Meanwhile, Tilton designed the two-story brick Renaissance Revival building. On April 8, 1911, Carnegie approved the project and donated $75,000 for the building's construction. The new building was dedicated on March 6, 1913, and it is considered "an excellent early twentieth century example of the architectural development of library planning and design." It was Tilton's only building in Iowa. Plans were made to enlarge the building in 1938, but the bond issue failed. The library remained in its cramped quarters until 1989 when it moved into a former bank building downtown. Ownership of the Carnegie building was transferred to a group of investors in 1996 who transformed it into apartments. It was listed on the National Register of Historic Places the following year.
