The wreath is intertwined with red ribbons which is done to express the festive spirit, while its evergreen leaves were symbolic of the everlasting life promised to the faithful by the birth of Jesus Christ. The circular shape was a reminder of the crown of thorns placed on His head by the Roman soldiers when they ridiculed Him as the 'king of the Jews'. Another reason for the wreath being used as part of celebrations related to the god Bacchus, whose worshippers were thought to have worn circular ivy crowns.

Another practical purpose for the wreath was that the evergreen boughs were believed to protect a home from evil spirits, which were thought to be plentiful during this dark time of the year. During the Middle Ages the red berries of holly were believed to keep witches out of the home; this is why holly became the traditional and lucky evergreen for the wreath-making.
