The West Side Spiritualist Church was a historic church building in Franklinton, Columbus, Ohio. The Spiritualist church was built in 1912 for the congregation of Harry Boerstler, who moved to the neighborhood in 1900 to bring hope to its working-class people. The congregation lasted until about 1948, and the building later housed the Boerstler Memorial Spiritualist Temple and the Greater Christ Temple Apostolic Church. After years of vacancy, the church building was approved to be demolished for affordable housing, to accompany an upscale mixed-use development nearby, despite opposition from preservationists.

The Franklinton Post Office is a historic building in the Franklinton neighborhood of Columbus, Ohio. It was listed on the National Register of Historic Places in 1973. Also known as the David Deardurff House, it was built of hand-hewed logs by Deardurff in 1807. The two-story house sits on a limestone foundation.

Engine House No. 6, also known as the East Franklinton Engine House, is a former Columbus Fire Department station in the East Franklinton neighborhood of Columbus, Ohio. The building was constructed in 1892, designed in the Romanesque Revival style by John Flynn. The station was decommissioned in 1966, and served as an electronics store from 1975 to 2014. It was listed on the National Register of Historic Places in 2016, accompanying planned renovations. The station has been planned to be sold since about 2016, originally to the Columbus Historical Society and Heritage Ohio, though the latter organization now plans to move to the Ohio History Center. The historical society acquired the building in November 2021, and is restoring it with plans to turn it into the city's first permanent local history museum. The station is one of two remaining Columbus fire stations designed by Flynn, and one of seven 1890s fire stations remaining in the city.

The General William Henry Harrison Headquarters is a historic building in the East Franklinton neighborhood of Columbus, Ohio.

The brick house was built in 1807 by Jacob Oberdier, one of Franklinton's first settlers. The house became especially important to the area from 1813 to 1814, when General William Henry Harrison, later the 9th President of the United States, used the house as his headquarters. It is the only remaining building in Ohio associated with Harrison.

The Sullivant Land Office is a historic building in the East Franklinton neighborhood of Columbus, Ohio. It was listed on the National Register of Historic Places in 1973 and the Columbus Register of Historic Properties, along with the Gen. William Henry Harrison Headquarters, in 1985. The small brick building was built c. 1822. Its original use was as a single-room real estate office, although it was later expanded. At the time of construction, Lucas Sullivant was selling and giving away pieces of land, and Franklinton became the county seat of Franklin County. The building is the only remaining structure associated with Lucas Sullivant in the Franklinton area. In the early 1980s, the Columbus Recreation and Parks Department moved the building from its original location at 714 W. Gay St. to 13 N Gift St., behind the William Henry Harrison house. The move was prompted because the building was endangered in its original location, with vandalism, deterioration, and plans to create a parking lot for a car dealership on the site.

The Lucas Sullivant House was the house of Lucas Sullivant, founder of Franklinton, Ohio. Franklinton, where the house was located, was Central Ohio's first white settlement, and a predecessor to and current neighborhood of the city of Columbus.Sullivant's house was near 700 W. Broad Street, in modern-day Columbus, Ohio. The brick house had two stories, each with two rooms. A walnut wood staircase connected the floors, supposedly transported from Philadelphia along with bricks and window panes. When it was built, it was largely among cabins and simple frame houses, making its high ceilings, grand staircase, and walnut floors unusual.The Sullivants first occupied the home in 1801, including Lucas, his wife Sarah Starling, and their three sons (born in 1803, 1807, and 1809). The family hosted numerous large events there, and its extensive backyard was the location for an 1813 conference between William Henry Harrison and indigenous leaders during the War of 1812. The Shawnee, Delaware, Seneca, and Wyandot attended the conference, and Tarhe the Crane agreed there that the groups would support the U.S. cause against the United Kingdom.Sarah died in 1814, and Lucas in 1823. The couple's sons maintained the house and expanded it, living there until 1854. Around this time, the Order of the Good Shepherd purchased it, making it into a convent. The house remained until 1964, when it was demolished to be replaced with a car dealership.Portions of the house were preserved, including its front door and doorway, donated to COSI, which was exhibited there for a time along with a recreation of the Sullivant house. In 2019, it was reported that the houses's ornate iron and wood balcony was salvaged as part of an interior wall of the car dealership, a wall made of the house's bricks. After the dealership closed in 2008, the bricks and balcony moved several times, and are today in storage.

Dorrian Green is a park by the Franklinton neighborhood of Columbus, Ohio. The park is part of the Scioto Mile network of parks and trails around downtown Columbus. Dorrian Green neighbors COSI, the city's science and children's museum. The park has numerous gardens: sensory, reading, butterfly and pollinator, and prairie. There is a plaza with an interactive fountain, flanked by two pavilions and flowering cherry tree groves. The park's northwest and southwest corners have salvaged limestone structures salvaged from the Central High School building that was repurposed and expanded into COSI. There are play areas for children and adults. "The Spectrum Tree", a kinetic tree-shaped sculpture, references Isaac Newton's discovery that sunlight contains the entire spectrum of colors. The park is named for Hugh J. Dorrian, the city's treasurer and auditor, working for the city for 52 years. Dorrian was a Franklinton resident, and helped revitalize the Short North, the Arena District, University District, Scioto Mile and Franklinton.

Central High School, also known as High School of Columbus and High School of Commerce, was a four-year secondary school (grades 9–12) located in Franklinton, Columbus, Ohio. It was a part of Columbus City Schools (at the time Columbus Public Schools). The last building was located at 75 South Washington Boulevard and opened in 1924. Prior to that, Central High School was located Downtown at East Broad and Sixth streets from 1862 until 1924. The school building operated on South Washington Boulevard closed in June 1982. In 1999, the school's historic façade was incorporated into the Center of Science and Industry (COSI), a science center designed by renowned architect Arata Isozaki. Isozaki used the high school's 1924 exterior facing downtown as its east entrance; a balance to the facility's progressively futuristic west entrance. On March 7, 1985, it was added to the National Register of Historic Places. It is considered part of the Columbus Civic Center Historic District.
