The city was named for a flint hill of rock that was in the way of the Charlotte and South Carolina Railroad, which was building a rail line from Charlotte to Columbia. Much of this rock was removed to make way for the railroad, which built a depot at the site that eventually became known as Rock Hill. The city dates its history back to April 17, 1852, the day the first Rock Hill Post Office opened, even though the town was not officially incorporated until 1870. Thus, Rock Hill celebrated its centennial in 1952 and its sesquicentennial in 2002.
