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.

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 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.
