49 gravestones were tipped over Monday evening at the Quaker Hill Cemetery.
Some need repair, others need to be replaced. A lot of flower arrangements were destroyed too.
Police are not releasing the names of the two girls they believe are responsible, who are 13 and 14-years-old.
Police say the teens also desecrated the inside of the church with harsh language written on the walls and splattered paint in the basement.
The two suspects stole a car from the Freedom Financial Group parking lot Tuesday morning.
The girls reportedly confessed to the crimes and are being held at a youth detention center in Charleston.
