In the early 1800s, the area that is now South Main Street was home to several significant buildings, including the Cullom House, Union Academy, Clinton Grove Academy, and Clinton Seminary. Main Street ended at Three Point, the Broad Street intersection, and that area was much lower than it is today. At the foot of the hill, the Town Springs Branch flows toward the Clinch River. When backwaters flooded, they stranded terrapins high and dry, giving the hill the name Terrapin Hill. Clinton Memorial Park now connects South Main Street to the Library/Community Center area near Town Springs.
