Ireland
Ireland is considered to be the birthplace of Halloween and it is here bonfires are lit and children go trick-or-treating. Traditional foods eaten include barnbrack sometimes with a ring hidden inside and chocolate apples.
UK
For a while, Halloween was moved to Guy Fawkes night although it is now celebrated in addition to bonfire night. Traditionally, home dwellers in rural areas left turnip lanterns outside their gate to ward away ghosts and spirits.
France
Unlike Ireland and the UK, France doesn’t actually celebrate it to honour the dead, but instead regards it as an American holiday. Originally kids went trick-or-treating store–to-store rather than house-to-house but it seems the later is starting to become more popular. Homeowners decorate their house and people display pumpkins or Jack-O-Lanterns
America
Halloween is not an official holiday and was brought to the States via Irish and Scottish immigrants. Since the 1930s kids have been dressing up and going trick-or-treating.
