The Dayton Daily News Building is a historic structure located at the corner of 4th and Ludlow Streets in Dayton, Ohio. It was designed by architect Albert Pretzinger for Dayton Daily News founder James M. Cox. According to Cox's autobiography, he was turned down for a loan by a local banker who told him “Newspapers have never been known to earn money. Of course we can’t accommodate you.” After being turned down for a bank loan to start the paper, Cox asked Pretzinger to "build him a damn bank" so it was modeled after the Knickerbocker Trust building in New York City. Among the most significant components of the three-story building are those surrounding the entrance: three bays wide, the facade features a set of Corinthian columns, a set of fluted columns in the Doric order that form a grand frontispiece around the entrance, and a partial pediment with a cornice supported by cornucopiae. Its walls are built of a mixture of wood and granite.The building was erected between 1908 and 1910 and expanded in the 1920s, 1950s and 1970s. The 1908 building was remodeled in 1989.

The Benjamin F. Kuhns Building is a historic commercial building on Main Street in downtown Dayton, Ohio, United States. Distinguished by its little-modified late nineteenth-century architecture, it has been named a historic site. Built of brick covered with a slate roof, the Romanesque Revival building features elements of stone and terracotta. Its facade is divided into five bays, each of which features a large arch, while the street-facing southern side is functionally a larger form of the facade. The building was designed by Peters and Burns, a Dayton-based architectural company, and constructed under the direction of Dayton contractors Beaver and Butt. During the building's early years, it was home to companies such as the Manhattan Clothing Store and Oleman's Department Store, which maintained premises there in the 1890s and 1910s respectively. However, the building was not always used for commercial purposes; an arts school operated in the building during the 1888-1889 schoolyear. Among the building's interior features is a mail chute, which according to local lore is one of the earliest installed in any building nationwide.Benjamin Kuhns, the building's namesake, moved from Lancaster, Pennsylvania to Dayton in 1855 at the age of thirty. By his fiftieth birthday, Kuhns was a prominent industrialist, having taken a small Dayton firm and turned it into a prominent manufacturer of agricultural equipment. He was also a prominent philanthropist, having been one of the primary founders of Miami Valley Hospital.The Benjamin Kuhns Building was listed on the National Register of Historic Places in April 1978, qualifying because of its historically significant architecture. By the early twenty-first century, the Kuhns Building had undergone a highly successful redevelopment process, but like the Kettering Tower and several other downtown buildings, it experienced foreclosure in 2010 after the corporation that owned it fell behind on the mortgage and on property taxes. In 2019, it was sold by the city of Dayton to a developer.

It was renovated to new apartments as part of the city block revitialation of the Dayton Arcade. Built for Theodore Lindsey, the Lindsey Building was constructed in 1917 at a time when Dayton was highly prosperous. During the late 1910s, the downtown was experiencing sustained growth, and numerous commercial buildings such as the Lindsey were being constructed. For much of its history, it has housed financial institutions, including the Miami Savings and Loan Company and the Mutual Home and Savings Association.In 1985, the Lindsey Building was listed on the National Register of Historic Places; by the early 2010s, it was one of approximately one hundred such locations in the city of Dayton. It qualified for designation in two separate ways: because of its architecture, and because of its place in local history, for it was deemed a leading example of the downtown's expansion in the early twentieth century.

Dayton ( ) is a city in and the county seat of Montgomery County, Ohio, United States. A small part of the city extends into Greene County. As of the 2020 census, the city proper had a population of 137,644, making it the sixth-most populous city in Ohio. Dayton anchors the state's fourth-largest metropolitan area, the Dayton metropolitan area, which had 814,049 residents. Dayton is located within Ohio's Miami Valley region, 50 miles (80 km) north of Cincinnati and 60 miles (97 km) west of Columbus. It is a principal city of the Dayton–Springfield–Sidney combined statistical area, home to a population of 1,086,512.Dayton was founded in 1796 along the Great Miami River and named after Jonathan Dayton, a Founding Father who owned a significant amount of land in the area. It grew in the 19th century as a canal town and was home to many patents and inventors, most notably the Wright brothers, who developed the first successful motor-operated airplane. It later developed an industrialized economy and was home to the Dayton Project, a branch of the larger Manhattan Project, to develop polonium triggers used in early atomic bombs. With the decline of heavy manufacturing in the late 20th century, Dayton's businesses have diversified into a service economy. Ohio's borders are within 500 miles (800 km) of roughly 60 percent of the country's population and manufacturing infrastructure, making Dayton a logistics hub.

The Montgomery County Courthouse (MCC), built in 1847, is a historic Greek Revival building located in Dayton, Ohio. It is referred to locally as the Old Courthouse. The limestone building, modeled on the 5th century BC Temple of Hephaestus in Athens, Greece, is the nation's best surviving example of a Greek Revival-style courthouse.The design was suggested by Dayton citizen Horace Pease, who had a book of sketches of the Acropolis in Athens which showed the Temple of Theseus, which he admired. Pease showed it to the Montgomery County Commissioners, who also were favorably impressed, and agreed it would be a good model for their new Courthouse. They hired architect Howard Daniels of New York to draw the plans in which he captured the form and beauty of the ancient Greek temple.The building, now restored, stands as a tribute to the leaders of old Dayton and to the artisans of the Miami Valley who built it. Dayton History, formerly known as the Dayton Historical Society and the Montgomery County Historical Society, is housed in the Old Court House. The courthouse was added to the National Register of Historic Places on January 26, 1970.
