All Souls' Day is observed on November 2 by Catholics all across the world.

In Roman Catholicism, All Souls' Day is a significant occasion. This date was chosen so that it would fall after All Saints Day- as a part of the celebrations of "Allhallowtide".

A hermit living there told him that amid the rocks was a chasm communicating with purgatory, from which perpetually rose the groans of tortured souls.
