Halloween is a very special time of year and takes on huge significance for a vast number of people in different ways. For many, it's a chance to dress up, wander the streets for a trick or treat session, gorge on candy and have a party, whereas for others it is a time of remembrance, of visits to ancestors' graves, or prayers at this holy time.

But what are the real origins and meanings of this festival that's commonly associated with darkness, witches, ghosts and ghouls? The oldest known Halloween celebration was the Celtic Samhain, a time when the souls and spirits of the dead would find it easiest to return to visit the living. Food was offered to keep the spirits happy and eventually the festival was formalised by the church as a time of remembrance in advance of All Saints Day.
