Two stories high, the house is built in a mixed architectural style: its structure is the post and beam characteristic of period Greek Revival structures, but the overall shape is that of early Italianate houses. Among its Italianate elements are its cubical shape, a shallow hip roof, and large eaves supported by double brackets. Greek Revival elements include the entrance portico, a large entablature with frieze windows, and sandstone window sills and lintels. Inside, the house features original its original walnut woodwork and a circular stairway wrought of cherry.For its first several decades, the McCrea House was almost alone; only one other nearby house was built circa 1840, for the surrounding neighborhood was primarily constructed in the last decade of the nineteenth century. Because of its historic architecture, the McCrea House was listed on the National Register of Historic Places in 1988. It lies one block east of the Watt-Groce-Fickhardt House, which is also listed on the National Register.

The Watt–Groce–Fickhardt House is a historic house in Circleville, Ohio, United States. Located along Main Street on the city's eastern side, it is a distinctive landmark and has been named a historic site. Circleville was platted in 1810 on a farm owned by Jacob Ziegler and Samuel Watt; later in the year, Ziegler sold his interest in the farm to Watt. With the community's rapid expansion, Watt sold more land; by 1820, only 148 acres (60 ha) remained in his ownership. Using the money from the land sales, Watt built a new farmhouse in 1826; two stories high, it is a brick structure with a stone foundation and a metal roof. When completed, it was a typical hall and parlor house. As Circleville continued to grow, Watt sold most of his remaining land in 1835; only 5 acres (2.0 ha) remained after the end of that year. Becoming a leading local businessman, he made an extensive addition to the house in 1852; this new structure took the form of an I-house. A smaller addition, built in 1885, is a frame structure attached to the original portion of the house.Today, the Watt–Groce–Fickhardt House remains a well-preserved example of antebellum architecture. In 1985, the house was listed on the National Register of Historic Places, qualifying because of its historic architecture and because of its connection to a later resident, John G. Groce, who was a leading member of local society.

The Luthor List Mound (also known as the "Burning Mound" or the "Signal Mound") is an archaeological site of the Adena culture in the southern part of the U.S. state of Ohio. Located in Pickaway County near the city of Circleville, this Native American mound sits along the Kingston Pike, southeast of Circleville in Circleville Township.As one of the largest burial mounds in Pickaway County, the Luthor List Mound is believed to contain the skeletons of many leading members of the society that built it. The mound's location on top of a small ridge, far from major bodies of water, is indicative that it was built by Adenan peoples, who often buried their chieftains in mounds such as the Luthor List Mound. Such mounds were typically built in stages: individuals would be buried within small mounds, and the resulting mound cluster would be covered with earth and converted into a single large mound.Unlike many of the region's conical mounds, the Luthor List Mound has seen very little damage since white settlement of the region. Located on a ridgeline, the mound sits at an elevation of 735 feet (224 m). With a diameter of at least 75 feet (23 m) in all directions, it is 12 feet (3.7 m) high; the erosion caused by the plows of past farmers has not damaged the Luthor List Mound because of its location — sitting atop the ridgeline and covered with trees, it is not an ideal farming location. In recognition of its archaeological value, the Luthor List Mound was listed on the National Register of Historic Places in 1974.

Circleville Memorial Hall is a historic community center and war memorial in the city of Circleville, Ohio, United States. Built in the years after the Civil War to remember the victims of the war, it has been named a historic site. In 1871, the state legislature enacted legislation to encourage the construction of Civil War memorials: the new law permitted Ohio's counties to gather money for the construction of memorials. This law permitted the construction of the Pickaway County memorial in Circleville twenty years later. Besides serving as a war memorial, the building has provided space for numerous community activities: the city's public library has long been housed on the first floor, while no meeting hall in the city is larger than the one in Memorial Hall's upper floors.Three stories tall, Memorial Hall is a brick building with a stone foundation and additional elements of brick and stone. The exterior is a clear example of the Richardsonian Romanesque style, due to elements such as the rounded archways, the heavy masonry construction and stone trim around its ribbon windows, its columns, and a massive corner tower. Inside, the community auditorium features a large balcony on the third floor.In late 1980, Memorial Hall was listed on the National Register of Historic Places, qualifying for inclusion because of its historic architecture.In recent years, through local funding, donations and state capital appropriations several renovations to the building have taken place including repairs to the roof, updating the HVAC to more modern standards and replacing exterior windows that leaked.

Redlands is a historic farmhouse near the city of Circleville in the south-central part of the U.S. state of Ohio. A grand home built in the middle of the 19th century, it has been named a historic site. Constructed in 1858, Redlands was originally the home of one of Pickaway County's more prosperous farmers, Jacob Valentine. The farmhouse itself is a brick structure, built of bricks manufactured on the farm; its foundation and minor elements are stone, and additional buildings on the property are weatherboarded. Its construction and its numerous decorative elements combine to make it typical of estates built for wealthy southern Ohio landowners soon before the Civil War. Particularly significant among these elements are the Greek Revival front porch, transoms above the windows and doors, its prominent fireplaces, and its grand front stairway.Besides the residence, the farmstead comprises three outbuildings: two historic buildings, which are vernacular structures that had been completed by 1860, and one that lacks historic integrity. In 1982, Redlands was listed on the National Register of Historic Places, qualifying because of its well-preserved historic architecture; the house and the two historic outbuildings were ranked as contributing, and the non-historic outbuilding was considered non-contributing. Crucial to the farm's designation was its status as an intact gentleman's estate from the end of the pre-Civil War period.
