Rocky Spring Burial Ground is the final resting place of early settlers who traveled the Great Wagon Road from Pennsylvania to what is now the Mint Hill area. In 1770, they established Clear Creek Presbyterian Church, now Philadelphia Presbyterian Church. The original log church stood several feet from the cemetery entrance but was consumed by fire in 1780, when a new building was constructed on Matthews-Mint Hill Road. The Rev. Alexander Craighead, a controversial minister who supported American independence, preached here. Among the graves within the stacked stone wall are Revolutionary soldiers, members of the Clear Creek Militia, and three signers of the Mecklenburg Declaration of May 20, 1775: Col. Adam Alexander, whose grave is marked by a headstone, John Foard, and John Query. Headstones marked "M.W. 1774" and "Elizabeth Robb 1792" are the oldest known graves.
