The primary document for the history of Terrace Park is "A Place Called Terrace Park" by Ellis Rawnsley. Rawnsley notes that the earliest human inhabitants of Terrace Park may have arrived as early as 12,000 years ago—the Paleo-Indians. Although "no traces of established settlements have ever been found," flints showing evidence of these nomadic people have been found in various locations in the areas surrounding Terrace Park. Circa approximately 1000 B.C.E., settlements appeared in Hamilton County, Ohio. According to Rawnsley, "Two thousand or more years ago, a primitive people built, in what is now Terrace Park, one of the largest of its kind of the 295 prehistoric earthworks ever found in Hamilton County." Mounds from the Adena Culture are found throughout a wide area which contains Terrace Park. In January 1789, Abraham Covalt established a small fortified settlement called Covalt Station in what is now Terrace Park. The area was surrounded by Shawnee settlements, and the Shawnee were hostile towards the white settlement in their midst. Covalt Station had to be abandoned in 1792 due to continuing attacks by the Shawnee, and white settlers only returned after General "Mad Anthony" Wayne defeated the Native AmericanWestern Confederacy at the Battle of Fallen Timbers and secured the Treaty of Greenville which ceded all of southern Ohio to the United States. Before roads and railroads connected the village to other nearby settlements, such as Milford, most residents of Terrace Park kept cattle and chickens, and engaged in other agricultural activities for their own subsistence, and had "homesteads" as opposed to the ordered residential village of today. Terrace Park was incorporated in 1893, and was the winter residence of the Robinson Circus until 1916. During the time that the circus wintered in Terrace Park, it was not unusual for elephants to roam free about the village, until the village council asked that they be restrained in 1910. The John Robinson Circus founded by John H. Robinson had its winter home in Terrace Park. The famous elephant Tillie was known to walk the streets of Terrace Park, where she is now buried.
