Why do Jews Place Stones On a Grave When They Visit a Cemetery and What Does the Custom Symbolize?

At the end of the movie Schindler’s List, the cast and some of the survivors visit the graves of those whom Schindler worked with.

Each person places a stone on the headstone, where Christians customarily place flowers.

This ancient Jewish custom dates back to Biblical times, when stones adorned graves as markers.

Today the stones reflect the importance of each soul and are a permanent record of all the people who come to pay their respects.
