The Union Literary Institute, located in rural Randolph County, Indiana, at 8605 East County Road 600 South, Union City, Indiana (at its founding, "two miles east of Spartanburg"), was a historic school founded in 1846 primarily for blacks by abolitionist Quakers and free blacks in three local communities. Only white students were allowed to attend the public schools in the state. The term "literary institute" at the time meant a non-religious school. This school was among the handful in the United States of the time that admitted both black and white students; it was the first in Indiana. The school closed in 1864 during the Civil War, when its only teacher enlisted in the United States Colored Troops. The students published a magazine from 1863-1864, which included articles by adults. The school re-opened after the war, operating until 1880; it closed because of declining enrollment. In 1924, after three decades of court challenges, the state acquired the building and the remaining 120 acres of the original site. The county had operated the structure as a segregated public school in the late nineteenth century. In the early 20th century, the structure was converted for use as a storage barn. In 2016 a historical marker was erected at the former school, noting its valuable history. It is within the Ohio River National Freedom Corridor.

The Greenville Mausoleum is an Egyptian Revival structure in Greenville, Ohio, United States. Built in 1913, this historic mausoleum is built of concrete covered with courses of limestone, resting on a foundation of granite and covered with a roof of ceramic tiles. Among its most distinctive elements are the marble pillars, topped with capitals of the Doric order, that line the main entrance. The main portion of the interior, built in a basilican style with multiple aisles, contains approximately four hundred concrete and marble crypts, and the building's wings house individual family crypts. It is lit by twelve clerestory windows under the roofline. Located along West Street adjacent to the cemetery's main entrance, the mausoleum was the brainchild of local doctor J.P. Collett. He chose a unique design for the structure: no other Egyptian Revival mausolea have been built near Greenville. Most historic cemetery buildings in western Ohio employed other styles of architecture; for example, the mausoleum in Fostoria and the Woodland Cemetery offices in Dayton were built in the Neoclassical and Romanesque Revival styles respectively. In recognition of its distinctive architecture, the mausoleum was listed on the National Register of Historic Places in 1976, being the fourth Darke County site to receive this recognition.
