Why do we wear costumes on Halloween?

The origin of Halloween goes back to the ancient pagan festival of Samhain, 2,000 years ago.

The Celts believed Samhain was a day when the gap between our world and the spirit world was blurred, making it easier for the spirits of the dead to return.

So to protect themselves, people dressed up in spooky costumes, hoping to scare off any spirits that they might bump into in the night.

The day was typically celebrated on or near what is 1 November in modern calendars. So very close to what is now Halloween!

Nowadays it's just a great reason to dress up and have fun so let us know who or what you've chosen for your costume!
