An outdoor nativity set proclaims your faith and reminds neighbors and friends of the true meaning of Christmas. Please browse our Spectacular Illuminated Outdoor Nativity Sets. The Nativity is the most important Christmas decoration in Italian tradition. The nativity is used as a remembrance of the joy of the birth of Jesus, and families and churches across the world happily and lovingly display nativity sets, both indoors and out. Some of our outdoor nativity sets are lit from within and around to create a beautiful glow reminiscent of a stained glass window in a Cathedral, while others are lit using mini lights, C7 lights, or rope lights.
