First National Bank (Mount Pleasant, Iowa)

Mount Pleasant City Hall is the official seat of government of the city of Mount Pleasant, Iowa, United States. This 1½-story stone structure was designed by Burlington, Iowa architect William Weibley, and constructed by local builder K.A. Bergdahl. It is an eclectic combination of Colonial Revival styles. For the most part it reflects Georgian Revival aesthetics with its symmetrical facade and the pilasters that flank the main entrance. The stepped ends of the gable roof and the projecting gable above the main entrance reflect the Dutch Revival influence. The random ashlar stone used in its construction was salvaged from the Seeley Memorial YMCA-high school that was destroyed in a 1932 fire. The city hall's construction in 1936 was a Works Progress Administration project. The east wing, which has been altered from its original appearance, originally housed the city's police and fire departments before they moved to their own buildings. City hall was listed on the National Register of Historic Places in 1991.

The Masters Building is a historic building located in Mount Pleasant, Iowa, United States. Completed in 1937, this two story, brick structure is an adaptation of the commercial Art Deco and Art Moderne styles. The decorative elements are found in the brick patterning and cast concrete panels on the facade. There are three other buildings on this same block that were built about the same time and use the same decorative techniques, with the Masters Building being the best example. This area was an expansion of the central business district after the construction of city hall across the street in 1936. A plumbing business, for which this building was constructed, was located on the first floor. There are three apartments on the second floor. The building was listed on the National Register of Historic Places in 1991.

The McCandless Building is a historic building located in Mount Pleasant, Iowa, United States. This three story brick Italianate structure was built in 1862 by local builder William McCandless. With the arrival of the railroad in 1856, Mount Pleasant was in need of new commercial buildings to house businesses and services that were opening in the expanding town. They were built on the north and east side of the town square. The Italianate was a prominent style used in the city at this time having been used by about a dozen buildings. This buildings features three round arch windows on the second and third floors with brick patterned hood molds. The storefront has been altered slightly, and the heavy wooden cornice that graced the top of the main facade was removed some time ago. The building was listed on the National Register of Historic Places in 1991.

The Harlan House Hotel is a historic building located in Mount Pleasant, Iowa, United States. It is associated with James Harlan, the first Republican to represent Iowa in the United States Senate (1855-1865, 1867–1872). He was also Secretary of the Interior (1865-1867). His daughter Mary was the wife of Robert Todd Lincoln, President Abraham Lincoln's only surviving son. Harlan built the oldest part of this building as his house in 1857. After his career as a Senator, he could no longer afford the house and bought another house in Mount Pleasant. Harlan built the first addition onto his old house and converted it into a hotel so he could support himself. He added onto the hotel two more times, c. 1880 and 1892. The first two additions are on the alley side of the building, and the third addition faces Jefferson Street. The middle section of the building with the bracketed cornice and mansard roof is the original house. Harlan moved into the hotel in the early 1890s and died here in 1899. A few minor alterations were made to the building in the 20th century. It was listed on the National Register of Historic Places in 1987.

National State Bank is a historic building located in Mount Pleasant, Iowa, United States. Because this two story, brick Italianate structure was built specifically as a bank, it features a chamfered corner, which was commonly used to designate a bank in the last quarter of the 19th century. However, it combines other features typical of an Italianate commercial building in an unusual way. The secondary facade has segmental arched windows that are regularly spaced, while the primary facade has the windows in a sophisticated arrangement that one would expect of an architect-designed building. (The potential architect of this building, or even its builder, are unknown.) The metal cornice has widely spaced brackets on the primary facade and more typically spaced on the secondary facade. It also lacks an identification pediment on the corner, which is typical of the style. The building was listed on the National Register of Historic Places in 1991.

The Union Block of Mount Pleasant, Iowa, was built by William McCandless in 1861. Historically it was used as offices and by the county courts. In the Union Block in 1869, Arabella A. Mansfield became the first woman in the United States awarded a license to practice law. The third floor housed the Opera House or Union Hall, a gathering place for the community. Early supporters of women's rights and civil rights spoke there, including Frederick Douglass, Bronson Alcott, Anna Dickinson, and possibly Elizabeth Cady Stanton.Preservation Iowa had listed Union Block on its most endangered buildings list because of its poor condition and lack of preservation plan.

The Brazelton House Hotel is a historic building located in Mount Pleasant, Iowa, United States. William P. Brazelton was an early leader in the city's development. He owned the Brazelton Banking House and he was one of the directors of the Brazelton House Company, which built the hotel. It is not clear, specifically, why the hotel bears his family name. The construction of the hotel in 1856 coincided with a building boom in Mount Pleasant with the extension of the Burlington and Missouri River Railroad into town. It was built with the belief that Mount Pleasant would need a large first class hotel, but it had financial problems from the beginning and went through a series of owners until it no longer functioned as a hotel about 1970. The building was listed on the National Register of Historic Places in 1986. In 2015 the upper floors were converted into apartments while the main floor continued to house retail businesses. At four floors it is the tallest building in the central business district. It was originally an "L" shaped building, but a 1911 renovation covered the courtyard and created a two-story lobby. The building exhibits elements of the Italianate style, notably found in the bracketed eaves.
