The practice of putting up special decorations at Christmas has a long history. In the 15th century, it was recorded that in London it was the custom at Christmas for every house and all the parish churches to be “decked with holm, ivy, bays, and whatsoever the season of the year afforded to be green”. The heart-shaped leaves of ivy were said to symbolize the coming to earth of Jesus, while holly was seen as protection against pagans and witches, its thorns and red berries held to represent the Crown of Thorns worn by Jesus at the crucifixion and the blood he shed.
