Also, Masses are usually said there on All Souls Day and other special Catholic Holidays. These help the souls that are in Purgatory enormously.
People also go there to pray. Sometimes I will go and pray for the souls there and sprinkle Holy Water on the graves.
I live near a Catholic Cemetary and pass it so many times a day. Each time I pass, I cross myself and pray, “Eternal rest grant unto them, O Lord, and may perpetual light shine upon them. May they rest in peace.” All this helps them get to Heaven quick.
Blessings,
