The Masonic Temple Theater (subsequently the Temple Twin Theaters, and in 2013 the Main Street Cinemas) is a historic building located in Mount Pleasant, Iowa, United States. Built in 1923, it combined both commercial and fraternal functions in one building. The theater company paid for the construction of the lower level, and the Masons paid for the upper level. The Masons continued to occupy the space until 1989 when they moved to another facility. The building was designed in the Neoclassical style by Owen, Payson & Carswell, and K.A. Bergdahl was the contractor who built it. Neoclassical features include the balustrade, the medallion with the Masonic insignia, volutes above the windows, the parapet roof, and the ornamental frieze and cornice. The building was listed on the National Register of Historic Places in 1991.

The Budde–Singer Building is a historic building located in Mount Pleasant, Iowa, United States. This three story, brick Italianate structure was built in 1882. It replaced a similar building that had been built in 1856 and destroyed in a fire. Its early Italianate style is unusual for this time period, but it fits into its streetscape with similarly designed buildings, including the neighboring Brazelton House Hotel. The Budde–Singer Building features round arched windows with brick patterned hoodmolds on the second and third floors, and a bracketed wooden cornice. The first floor storefront has been somewhat altered, and the exterior of the building has been painted since about 1909. It was listed on the National Register of Historic Places in 1991.

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.

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.

Henry County Savings 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. Other features typical of an Italianate commercial building include segmental arched windows, a corbeled brick frieze, and a bracketed metal cornice. The building was listed on the National Register of Historic Places in 1991.

The Zuhn Building is a historic building located in Mount Pleasant, Iowa, United States. Completed in 1886 a block east of the town square, this three story, brick, Italianate structure replaced a single story building that had housed the Mount Pleasant Carriage Works. H.A. Zuhn had that building torn down and this one built so he could expand his business. He used this facility to manufacture and repair vehicles. The only decorative element of the building is the bracketed metal cornice with date and pediment caps across the top of the facade. The double storefront has been altered somewhat over the years. 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.

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 Timmerman–Burd Building is a historic building located in Mount Pleasant, Iowa, United States. The previous building on this lot was destroyed in a fire in 1883 and Henry Timmerman had this building constructed to replace it the same year. The two story brick structure is one of several building facing the town square in the Italianate style. This building features a single storefront, and four segmental arch windows on the second floor with simple brick patterned hood molds. The bracketed metal cornice at the top of the main facade was mass-produced and likely ordered from a catalog. Burd worked for Timmerman and took over the business. This building housed a shoe store as late as the 1990s. It was listed on the National Register of Historic Places in 1991.

The Louisa Building is a historic building located in Mount Pleasant, Iowa, United States. Completed in 1901, this two story, brick structure features a transitional design between the Italianate, that had been popular here, and the Neoclassical that would replace it in popularity. It has a triple storefront with three sets of three windows on the second floor. In place of hood molds, which were typical of the Italianate, each window has a heavy rusticated stone lintel. The metal cornice across the top of the facade is simpler in its decorative elements than earlier Italianate cornices. This building replaced the Ambler Block, which had been destroyed in an 1882 fire. The lot had remained empty in the intervening years. The building was listed on the National Register of Historic Places in 1991.
